PLC in CoPS?
PLC doesn't apply to CoPS:
– 'In other industries (e.g., military and commercial aircraft, large turbine generators), automated mass production is never achieved and most innovation is product-oriented' (Michael Porter, p194, Competitive Advantage: 1985) – 'high volume, process intensive stages of the product life cycle may never occur…Thus competitive strategies are likely to centre upon the design and development 'stages' of the conventional product life cycle' (Miller and Hobday et al, 1995)

W H I T E P A P E R Tough Decision:On-Line or Line-Interactive UPS? How to Choose the Right Protectionfor Your NetworkExecutive SummaryIn today’s data-driven, technology-dependent world, noorganization – large or small – can afford the financialcost, customer frustration and business disruption causedby network downtime. That means complete protectionagainst all potential power problems, including blackouts,brownouts, surges and line noise, is a must. The goodnews is there are plenty of options for protectingyour network. But with so many different types ofuninterruptible power supply (UPS) systems available,the challenge is selecting the one that best matches yourneeds and budget. For 120 V equipment loads up to3,000 VA, on-line, double-conversion UPS systems andnetwork-grade line-interactive UPS systems both offerhigh-performance protection. This document provides anin-depth comparison to help you determine which UPStype is the better choice for your application.Table of ContentsHow Much Protection is Enough? (3)What You Should Know about On-Line, Double-Conversion UPS Systems (4)How They Work (4)The Biggest Benefits (5)Things to Think About (6)What You Should Know about Network-Grade Line-Interactive UPS Systems (7)How They Work (7)The Biggest Benefits (8)Things to Think About (9)What Do the Similarities and Differences Mean for Your Application? (10)Sample UPS System Comparison (11)The Tipping Point (12)About Tripp Lite (12)How Much Protection is Enough?IT is the lifeblood of virtually any business in today’s highly connected, data-centric environment. Whether you have a few server racks, a back-office network closet or a small data center, you’re under constant pressure to keep your network up and running. And you’re no doubt well aware just how vital the right UPS system is to protecting your equipment against damage, downtime and data loss.UPS systems deliver varying levels of protection, ranging from basicbattery backup and surge protection to on-line operation and zero transfer time to battery. Factors that influence your selection include:• The amount of power your connected equipment requires• The sensitivity of your equipment• The length of backup runtime you need• Whether you have whole-site generator backup• The voltage of the equipment you’re supporting• How critical your application is• Your available budgetBoth line-interactive and on-line, double-conversion UPS systemsprovide excellent protection for 120 V equipment loads up to 3,000 VA. In addition to providing battery backup power, they automaticallyregulate high- and low-voltage conditions to ensure reliable operation without relying on their batteries. And both types are relatively simple to install, operate and maintain, even for a one-person IT department or an organization with no IT department at all. Although the UPS systems share many similarities, there are also key differences that are important to understand when deciding which type is most appropriate for your particular application. In some cases, you’ll even find that an on-line UPS is the right choice for protecting some of your equipment and a line-interactive UPS is the right choice for protecting other equipment.Your critical IT equipment requiresaround-the-clock protection.of the UPS.On-line UPS systems have an automatic AC bypassto keep equipment powered if there is an internalfault or overload.The Biggest BenefitsOn-line UPS systems provide top-quality protection for even your most mission-critical equipment. Here are several reasons why:• Isolation of sensitive equipment. The continuous double-conversion process effectively isolates sensitive equipment from power problems. • Zero transfer time. Since DC-to-AC power conversion is integrated into normal operation, there is zero transfer time (0 milliseconds)between the loss of AC input power loss and the supply of AC backuppower converted from stored DC battery power. Zero transfer timeensures that there is no risk of losing or corrupting valuable data. • Nearly perfect voltage regulation. On-line UPS systems set thestandard for voltage regulation, continuously supplying output within ±2% of the nominal (ideal) voltage.• Battery-independent restart. On-line models with this feature are able to pass through power after utility power is restored, even if the battery dies. This eliminates the need for manual restarts at remote sites in the middle of the night.• Intelligent operation. Power management software enables remote monitoring and management of energy usage and detailed reporting on operating conditions, as well as the ability to reboot unresponsive equipment from anywhere, anytime.• Frequency regulation and conversion. When utility power goes out and generator power kicks in, the frequency of the generator output can be erratic. The double-conversion process ensures that frequency is regulated to prevent equipment damage. Most on-line systems also support frequency conversion from 60 to 50 Hz and vice versa. • Extended runtime. External battery packs increase battery backup runtime to last through lengthy power outages. Expandable battery packs support daisy-chaining to increase runtime to match any practical requirement.Extending runtime is as simple asplugging in an external battery pack.connected equipment, while the inverter/charger charges the battery for emergency use during an outage (blackout).If voltage fluctuates to abnormally low levels (called a power sag or brownout) or abnormally high levels (called an overvoltage), line-interactive UPS systems use the built-in voltage regulator to increaseor decrease the output voltage to acceptable levels. This feature isalso known as automatic voltage regulation (AVR). As long as the input voltage is within the AVR correction range, line-interactive UPS systems regulate the output voltage without using battery power. This is an advantage because frequent switching to battery drains the reserve power intended for an outage and causes wear and tear that reduces the battery’s useful lifespan.During an outage, the line-interactive UPS converts the stored DC (battery) power into regulated AC output power to support the connected equipment load. Network-grade models provide sine-wave output from battery.* Line-interactive models intended for desktop applications are usually not recommendedfor network applications. Desktop models typically do not offer rack installation and sine wave output, nor the same degree of voltage regulation, manageability, serviceability, expandability, availability and resilience as network-grade line-interactive models.The Biggest BenefitsNetwork-grade line-interactive UPS systems provide highly reliable protection to your network and connected equipment. Benefits include:• Extremely fast transfer time. Because the inverter is not active during normal operation, there’s a tiny delay – typically 2 to 4milliseconds – during the transfer from AC power to battery backup power. The delay is barely detectable, however, and it is rare for it to cause issues with connected equipment.• Excellent voltage regulation. Network-grade line-interactive UPS systems typically regulate voltage within +6% to -14% of normalvoltage, which is more than acceptable for almost all equipment. • Intelligent operation. Like on-line UPS systems, line-interactive models support power management software to help you remotely monitor energy usage and detailed operating conditions, as well as reboot unresponsive equipment from anywhere, anytime.• Extended runtime. External battery packs increase battery backup runtime to last through lengthy power outages. Expandable battery packs support daisy-chaining to increase runtime to match any practical requirement. (Not all line-interactive UPS models support extended runtime, so confirm availability in the specifications if you need this feature.)• Operating efficiency. Line mode efficiency is as high as 99%, reducing energy costs and heat output.Power management software helps you remotelymonitor energy usage and operating conditions, aswell as reboot unresponsive equipment.Things to Think About Although network-grade line-interactive UPS systems are comparable inmany ways to on-line models, they also have some key differences:• First, the output voltage regulation is less precise than on-line model, although still compatible with almost all servers andnetwork equipment.• Second, the transfer time is excellent, but it is a notch below thestandard set by on-line models. • Third, most line-interactive UPS systems do not have anautomatic bypass, so equipment will not remain powered in case of an internal fault or overload. In practice, however, the inherent reliability of the line-interactive architecture makes this feature somewhat less important.• Last but not least, line-interactive models do not have battery-independent restart capability, meaning someone may need to manually restart the UPS when utility power is restored after an outage that exceeds the runtime.On the plus side, line-interactive UPS systems are very cost-effective, requiring less investment in capital and operating costs than their on-line counterparts. And because they produce less heat than on-line models, they are well-suited for installations with limited cooling capacity.Network-grade line-interactive UPS systems provideexcellent power protection, typically at lower costthan on-line models.recommended for:• Basic and price-sensitive network applications• Applications requiring enhanced efficiency• Applications requiring reduced heat output• Locations with relatively good on-site power• Locations with whole-site generator backupBecause of its continuous double-conversionprocess, an on-line UPS system has zero transfertime between a power failure and the delivery ofbattery backup power. The transfer time of aline-interactive UPS system is extremely fast(2 to 4 milliseconds) and does not pose a problemfor most applications.Network-Grade Line-Interactive UPS SMART1500RMXL2UA On-Line, Double-Conversion UPS SU1500RTXLCD2U120 V, 1,500 VA (1,350 W)120 V, 1,500 VA (1,350 W)Pure Sine WaveSample UPS System Comparison:11.Tough Decision: On-Line or Line-Interactive UPS?12.About Tripp LiteCustomers in the IT, telecom, industrial, commercial,corporate, healthcare, government and educationsectors choose Tripp Lite for complete solutionsto power, protect, connect and manage servers,network hardware and other equipment in datacenters and related facilities.

Increasing the capacitance value makes thestarting time (t s) later. Decreasing the capacitance value makes the starting time (t s) earlier.C3 (C4)Bootstrap capacitorsDecreasing the capacitance value lowers output at low frequencies.

BTL applications normally requireoutput capacitors.C9 (C10)Switching distortion compensating capacitorsCompensates switching distortion which occurs at a high frequency of 10kHz. Ceramic capacitor of0.01µF is recommended. If no problem arises in terms of radio-casette recorder design or tone, it isunnecessary to use these capacitors.C11Filter capacitor (A)Ripple filter circuit provided in power supply line. A capacitance value of 220µF is recommended.Ripple rejection SVRR starts to be saturated at 47µF. The starting time and pop noise generated at thetime of power supply ON must be considered when fixing the capacitance value. A capacitance value of100µF to 220µF is usable.C12Filter capacitor (B)Ripple filter circuit provided in bias circuit. A capacitance value of 100µF is recommended. 3V sufficesthe breakdown voltage of this capacitor. This capacitor is for ripple rejection at transient state and rejectsnoise “buzz” generated when the above-mentioned filter circuit provided in power supply line is satu-rated due to large ripple and supply voltage drop induced at the time of start of the motor connected topower supply line. If the motor is satisfactory in performance and the power supply regulation includingripple is 500mVrms or less, it is unnecessary to use this capacitor. If noise “buzz” is not offensive to theear, it is unnecessary to use this capacitor. In this case, other basic performances are not affected ad-versely.Feaures of IC Contents and Functions of Other Pins(a)Since the input circuit uses PNP transistors and the bias voltage is set nearly equal to 0, no input couplingcapacitor is required, thereby enabling direct coupling. However, if slider contact noise of the variable resistor presents any problem, connect a capacitor in series with input.(b)Various ideas embodied in the idling circuit enable reduced I CCO and prolonged battery life. Since the non-operating level of the idling circuit is made equal to that of the amplifier, crossover distortion does not worsen at the time of reduced voltage.(c)The open loop voltage gain is lowered and the negative feedback amount is made small to assure stable opera-tion. Radiation to the radio-frequency stage is made less by soft clipping.(d)Capacitors for oscillation compensation are contained as a means of reducing the number of external parts.10pF×2 and 2pF×2 are used. Hig roll-off frequency f H (–3dB point) depends on these capacitance values.(f H=28kHz)(e)A thermal shutdown (THD) circuit is contained to prevent the IC from being destroyed by abromal heat genera-tion attributable to insufficient heat dissipation. Pin (11) is used as THD control pin. Biasing pin (11) externally makes the operating temperature lower ; and connecting a resister across pin (11) and (10) makes the operating temperature higher. If pin (11) is connected to GND, the thermal shutdown circuit stops operating.(f)The pin assignment is carefully considered so that no destruction takes place even if power supply is applied at astate where adjacent pins are shorted by solder bridge, etc. Even 180°C-rotated insertion causes no destruction.(g)Collector pins (5), (16) and base pins (6), (15) for predrive can be conveniently used in applications. For oscilla-tion compensation occuring when operated at a lowered gain, connect a capacitor across the pins (4) and (6) anda capacitor across pins (15) and (16). For fH compensation occuring when operated at a lowered gain, connect acapacitor across pins (4) and (6) and a capacitor across pins (17) and (15). Further soft clippling and prevention of waveform distortion at high frequencies are attained by connecting a series circuit of diode (DS442) andresistor (10kΩ) across pin (6) and GND and the same across pin (15) and GND.Continued on next page.Continued from preceding page.(h)Feedback resistance R NF is contained and the voltage gain is fixed at 50dB so that the variations in the voltagegain can be minimized. The gain can be lowered by connecting R NF externally.(i)Biasing pin (12) as shown below causes DC audio muting to be applied, thereby cutting off the IC.
