IC695PSD140D  多用途40瓦电源 用于负载分担和冗余应用

电源IC695PSA140是一款多用途40瓦电源，从85至264 VAC或100 VDC至300 VDC的输入电压源工作。
该电源提供三种输出:
■+5.1 VDC输出;
■+24直流继电器输出，可用于输出继电器模块上的电路供电。
■+3.3 vdc。该输出由目录号为IC695的RX3i模块在内部使用。
该电源适用于负载分担和冗余应用。多达4个多用途电源(PSA140和/或PSD140)可用于PACSystems RX3i (IC695目录号)通用背板。当需要安装的模块数量超过单个电源的容量时，请使用这些电源。本电源模块占用两个背板槽位。

以下信息适用于带有UL危险场所标志的产品:
•警告-爆炸危险-替代组件可能会损害i类第2部分的适用性;
•警告-爆炸危险-当在危险场所时，在更换或接线模块之前关闭电源;和
•警告-爆炸危险-不要连接或断开设备，除非电源已关闭或已知该区域无危险。
•标有i类a、b、c和d组2类危险场所的设备仅适用于i类2类a、b、c、d组或非危险场所
•控制端子的拧紧扭矩范围为9.6-11.5 in。只使用额定温度为90°C的电线。一定要遵守模块提供的任何附加额定值。
•电池:更换松下配件号电池。BR2477A。使用其他电池可能有火灾或爆炸的危险。“小心，如果不当使用，电池可能会爆炸。”“请勿充电、拆卸或在火中处置”。正确的电池类型可作为附件套件IC698ACC701。

电源上的4个led指示:
■能量(绿色/琥珀色)。绿色常亮，表示背板有电源供电。当这个LED是琥珀色时，电源被应用到电源，但电源开关关闭。
P/S故障(红色)。当这个LED亮起时，它表明电源已经失效，不再向背板提供足够的电压。
■超温(琥珀色)。当此LED亮起时，表示电源接近或超过其最高工作温度。
■过载(琥珀色)。当此LED亮起时，表示电源在至少一个输出上接近或超过其最大输出能力。
出现“过温”、“过载”、“P/S故障”时，CPU故障表会显示相应的故障信息。

5.1 VDC输出电子限制为7安培。3.3 VDC输出限制为10安培。如果发生过载(包括短路)，则内部检测并关闭电源。由于它是为冗余应用而设计的，因此该电源在故障条件下锁定“OFF”，并且不会自动尝试重新启动。输入电源必须循环以清除锁存故障。但是，如果电源在非冗余应用中使用，需要自动重新启动，则可以安装跳线插头。
在输入线路中提供一个内部可融合的链路作为备份。电源通常在熔断前关闭。可熔连接还可以防止内部电源故障。出现“过温”、“过载”、“P/S故障”时，CPU故障表会显示相应的故障信息。没有额外的指示，如果电源熔断。

IC695PSD140

Power Supply IC695PSA140 is a multi-purpose 40-Watt supply that operates from an input voltage source in the range of 85 to 264 VAC or 100 VDC to 300 VDC.
This power supply provides three outputs:
■ +5.1 VDC output,
■ +24 VDC relay output that can be used to power circuits on Output Relay modules.
■ +3.3 VDC. This output is used internally by RX3i modules with IC695 catalog numbers.
This Power Supply is suitable for use in load-sharing and redundancy applications. Up to 4 Multi-purpose power supplies (PSA140 and/or PSD140) can be used in a PACSystems RX3i (IC695 catalog number) Universal Backplane. Use these Power Supplies if the number of modules required exceeds the capacity of one Power Supply. This Power Supply occupies two backplane slots.

The following information is for products bearing the UL marking for Hazardous Locations:
• WARNING – EXPLOSION HAZARD – SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 2;
• WARNING – EXPLOSION HAZARD – WHEN IN HAZARDOUS LOCATIONS, TURN OFF POWER BEFORE REPLACING OR WIRING MODULES; AND
• WARNING – EXPLOSION HAZARD – DO NOT CONNECT OR DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NONHAZARDOUS.
• EQUIPMENT LABELED WITH REFERENCE TO CLASS I, GROUPS A, B, C & D, DIV. 2 HAZARDOUS LOCATIONS IS SUITABLE FOR USE IN CLASS I, DIVISION 2, GROUPS A, B, C, D OR NON-HAZARDOUS LOCATIONS ONLY
• The tightening torque range for the control terminals is 9.6-11.5 in. lb. Use only wire rated for 90°C. Be sure to observe any additional ratings that are provided with the modules.
• Batteries: Replace Battery with Matsushita Part No. BR2477A Only. Use of another battery may present a risk of fire or explosion.” “Caution, Battery may explode if mistreated. Do Not recharge, disassemble or dispose of in fire”. The correct battery type is available as Accessory Kit IC698ACC701.

Four LEDs on the Power Supply indicate:
■ Power (Green/Amber). When this LED is green, it indicates power is being supplied to the backplane. When this LED is amber, power is applied to the Power Supply but the Power Supply switch is off.
■ P/S Fault (Red). When this LED is lit, it indicates the Power Supply has failed and is no longer supplying sufficient voltage to the backplane.
■ Over Temperature (Amber). When this LED is lit, it indicates the Power Supply is near or exceeding its maximum operating temperature.
■ Overload (Amber). When this LED is lit, it indicates the Power Supply is near or exceeding its maximum output capability on at least one of its outputs.
The CPU Fault Table shows a fault if any Overtemperature, Overload, or P/S Fault occurs.

The 5.1 VDC output is electronically limited to 7 Amps. The 3.3 VDC output is limited to 10 Amps. If an overload (including short circuits) occurs, it is sensed internally and the Power Supply shuts down. Because it is designed for redundancy applications, this Power Supply latches “OFF” in fault conditions and will not automatically try to restart. Input power must be cycled to clear a latched fault. However, if the Power Supply is used in a non-redundant application where automatic restarting is required, a jumper plug can be installed.
An internal fusable link in the input line is provided as a backup. The Power Supply usually shuts down before the fusable link blows. The fusable link also protects against internal supply faults. The CPU Fault Table shows a fault if any Overtemperature, Overload, or P/S Fault occurs. There is no additional indication if the Power Supply fusable link blows.
