The 302 Series do not respond to momentary temperaturefluctuations below the selected temperature.•Universal application. The 302 Series can be used in all areas for any type of occupancy.•Self-restoring.•Hermetically sealed, shock resistant,corrosion resistant, and tamper-proff.ListingsListings and approvals below apply to the 302 Series M Rate-Anticipation Heat Detectors. In some cases, certain modules may not be listed by certain approval agencies, or listing may be in process.Consult factory for latest listing status.•UL Listed: file S539 & E35018A.•CSFM approved: file 7270-0021:001.•FM approved: file302 SeriesRate-Anticipation Heat DetectorsDescriptionThe Thermotech 302 Series rate-anticipation heat detectors operate within a conrolled range of two to three degrees of their set points,regardless of the speed or rate of temperature rise. These detectors are available in either 135° F or 194°F ratings.The 302 Series are normally-open devices designed especially for fire detection and alarm systems.Principles of OperationThe 302 Series rate-anticipation heat detectors respond andactivate the fire alarm immediately whenever the ambient temperature reaches the preset temperature setting. Under rapid heat rise conditions,the rate-anticipation feature enables the detector to respond one to three degrees ahead of the setting. At the same time, however, it does not respond to momentary temperature flucuations below the selected protection level,thus eliminating false alarms. When temperature drops back down below the protection level, the detector automatically resets itself.Application Information302 Series detectors have a smooth-ceiling UL rating of 50' x 50' (15.24 x 15.24 meters) and are the only type of heat detectors having such a rating on both fixed temperature and rate anticipation.6935p h o 1.j p g302 Series CS-2519 09/01/06Page 2 of 2Specifications and wiring information are provided for information only and are believed to be accurate.

It is important that the top module is connected in the correct orientation as shown in Figure 2-1. The EXPAND0 written on the STK520 top module should match the EXPAND0 written beside the expansion header on the STK500 board.Figure 2-1. Connecting STK520 to the STK500 BoardNote:Connecting the STK520 with wrong orientation may damage the board.2.1.1Placing anAT90PWM3 on theSTK520The STK520 contains both a ZIF socket for a SO32 package. Care should be taken so that the device is mounted with the correct orientation. Figure 2-2 shows the location of pin1 for the ZIF socket.Using the STK520 Top ModuleFigure 2-2. Pin1 on ZIF SocketCaution: Do not mount an AT90PWM3 on the STK520 at the same time as an AVR ismounted on the STK500 board or at the same time as an AT90PWM2 is mounted on theSTK520 board. None of the devices might work as intended.2.1.2Placing anAT90PWM2 on theSTK520The STK520 contains both a ZIF socket for a SO24 package. Care should be taken so that the device is mounted with the correct orientation. Figure 2-2 shows the location of pin1 for the ZIF socket.Figure 2-3.

None of the devices might work as intended.Using the STK520 Top Module2.2Programming theAVR The AVR (AT90PWM2, AT90PWM3...) can be programmed using both SPI and High-voltage Parallel Programming. This section will explain how to connect the programming cables to successfully use one of these two modes. The AVR Studio STK500 software is used in the same way as for other AVR partsNote:The AT90PWM3 also support Self Programming, See AVR109 application note for more information on this topic.2.2.1In-SystemProgramming Figure 2-4. In-System ProgrammingTo program the AT90PWM3 using ISP Programming mode, connect the 6-wire cable between the ISP6PIN connector on the STK500 board and the ISP connector on the STK520 board as shown in Figure 2-4. The device can be programmed using the Serial Programming mode in the AVR Studio4 STK500 software.Note:See STK500 User Guide for information on how to use the STK500 front-end software for ISP Programming.Using the STK520 Top Module2.2.2High-voltageProgramming Figure 2-5. High-voltage (Parallel) ProgrammingTo program the AVR using High-voltage (Parallel) Programming, connect the PROGC-TRL to PORTD and PROGDATA to PORTB on the STK500 as shown in Figure 2-5. Make sure that the TOSC-switch is placed in the XTAL position.As described in the STK500 User Guide (jumper settings), mount the BSEL2 jumper in order to High-voltage Program the ATmega devices. This setting also applies to High-voltage Programming of the AVR.The device can now be programmed using the High-voltage Programming mode in AVR Studio STK500 software.Note:See the STK500 User Guide for information on how to use the STK500 front-end software in High-voltage Programming mode.Note:For the High-voltage Programming mode to function correctly, the target voltage must be higher than 4.5V.Using the STK520 Top Module2.3JTAGICE mkIIConnector See the following document :“JTAGICE mkII Quick Start Guide” which purpose is “Connecting to a target board with the AVR JTAGICE mkII”.This note explains which signals are required for ISP and which signals are required for debugWIRE.Figure 2-6 shows how to connect the JTAGICE mkII probe on the STK520 board. Figure 2-6. Connecting JTAG ICE to the STK520The ISP connector is used for the AT90PWM3 built-in debugWire interface. The pin out of the connector is shown in Table 2-1 and is compliant with the pin out of the JTAG ICE available from Atmel. Connecting a JTAG ICE to this connector allows On-chip Debug-ging of the AT90PWM3.More information about the JTAG ICE and On-chip Debugging can be found in the AVR JTAG ICE User Guide, which is available at the Atmel web site, .分销商库存信息: ATMELATSTK520。

In the Times 1 Mode when “B”is at a low level, a negative going transition at “A”will cause the counter to count in the positive direction. When “B”is at a high level, a negative going transition at “A”will cause the counter to count in the negative direction.TABLE I illustrates the level settings of the Mode Select Inputs for the various modes of Bi-Directional counting. The Times 2 Mode works like Times 1 Mode except the counter changes on a positive going transition at “A”, as well as on a negative going transition at “A”. There are also two Divide-By Modes which prescale the display by 10 or by 100. This results in the capability of displaying the 7th and 8th digit of the internal counter. (Along with Times 2, this gives an MODES OF OPERATIONANTI-COINCIDENCE SUMMING MODESFor Anti-Coincidence Summing, input “A”and input “B”both serve as Add Inputs. These modes effectively separate count pulses which may simultaneously occur at the two inputs. The unit then processes the count pulses into a string of time-separated pulses so that the internal counter will not lose any counts. Both inputs respond to the negative going transition in the Times 1 Mode.TABLE III illustrates the level settings of the Mode Select Inputs for the various modes of Anti-Coincidence Summing.Note: The maximum count rate for all Anti-Coincidence counting modes is 20KHz.TABLE IIITYPICAL APPLICATIONSPANEL BEZEL KIT FOR THE SUPER SUB-CUB P/N HWK50000)This kit provides a convenient way to adapt the SUPER SUB-CUB for panel mounting.

专为高性价比AC/DC转换器设计。
在85V-265V的宽电压范围内提供高达12W的连续输出功率，峰值输出功率更可达18W。
优化的高合理性的电路设计结合高性能价格比的双极型制作工艺，最大程度上节约了产品的整体成本。
该电源控制器可工作于典型的反激电路拓扑中，构成简洁的AC/DC转换器。
IC内部的启动电路被设计成一种独特的电流吸入方式，可利用功率开关管本身的放大作用完成启动，这显著地降低了启动电阻的功率消耗；而在输出功率较小时IC将自动降低工作频率，从而实现了极低的待机功耗。
在功率管截止时，内部电路将功率管反向偏置，直接利用了双极性晶体管的CB高耐压特性，大幅提高功率管的耐电压能力直到700V的高压，这保证了功率管的安全。
