艾莫廷U8030系列三出力DC电源供应器数据册说明书
Agilent U8030 SeriesTriple-Output DC Power SuppliesData SheetAgilent extends its family of basic DC power supplies to include a one of a kind power supply that offers up to 375 W power at three outputs. Equipped with output sequencing capability, it allows you to generate output sequences even with minimal programming skills. Each power sup-ply is also built with excellent load regulation and clean output noise for continued stability. With these and many other features, you get a solid and reliable triple-output power sup-ply at an unsurpassed performance.The U8030 series offers twomodels- the U8031A and U8032A, each with different voltage andcurrent ratings to cater to your needs. Both models are well-regulatedcompact bench-tops with total output of 375 W, making it an ideal power source alternative in electronics manufacturing, research and develop-ment as well as education sector.Generate power supply output sequences -No ExtensiveProgramming Skills NecessaryThe output sequencing capability is carefully thought out for your convenience and ease when operating. Designed to perform automation function, our U8030 series is well-suited even for those with minimal programming skills. With easy-to-use knob and intuitive keypads, you can now set yourdesired output sequences for margin test, burn-in test and other general purpose tasks in an industrial setting.Higher Power. Better Reliability.Unrivalled Performance.Key Features• Provides total power of 375 W for three outputs• Output sequencing capability• Excellent load and line regulation (CV: < 0.01% + 2 mV; CC: < 0.02% + 2 mA) ensures stable output • Provides clean output with≤ 1 mVrms (0.5 mVrms typical) noise• Fast < 50 µs transient response for stable testing• Dual display shows both voltage and current reading• Over-voltage and over-current protection• Security features: keypad lock and physical lock mechanismUnrivalled Performance- With Low Output Noise and Excellent Load RegulationThe U8030 series provides excellent load and line regulation(CV: < 0.01% + 2 mV; CC: <0.02% + 2 mA) to ensure stable output even when load changes. This is crucial especially when dealing with noise-sensitive circuits that demand clean power. At a wide bandwidth of 20 Hz to 20 MHz, our bench power supplies continue to provide clean output at the lowest Vrms ≤ 1 mVrms (0.5 mVrms typical), leaving your signals uncontaminated and ensuring minimal interference to your Device-Under-Test (DUT).Added Safety Features-With OVP, OCPand Physical LockMechanismSafety is an important considerationwhen dealing with power. Users maynot only want to protect themselvesfrom exposure to current, but alsothe additional costs incurred to theirinvestment (DUT). Our U8030 seriespower supplies are integrated withan array of security features such asover-voltage (OVP) and over-current(OCP) protection to mitigate theserisks.Additionally, security features suchas keypad locking capability preventsaccidental front panel usage whilephysical lock mechanism which isstrategically located at the rear ofthe unit provides secure instrumentstorage.Differentiated Features-Allowing You to WorkBetterBoth models of the U8030 seriescome with a set of features to suityour needs while remaining easy touse. The LCD screen displays bothvoltage and current readings in a one-view panel while the all ON/OFF but-ton allows multiple outputs to be con-trolled simultaneously. Additionally,the auto-track feature simplifies setupbetween output 1 and output 2. Withthese, you get a solid bench powersupply plus a set of convenient andeasy to use features.Figure 1.

Next, let’s talk about glass. Glass is very smooth. It feels cool to touch. It is not as heavy as metal. It is hard. But it is not strong. It breaks very easily! Then why do we use it? We use it because it is clear! You can see through glass! That’s why we use itfor windows. That’s also why we use it for glasses.
