Product Description

https://www.instrumart.com/assets/IC695PSA140-Datasheet.pdf

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.

Product parameter

• 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.

Application field

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.

In a non-redundancy application, where automatic restarting may be appropriate, a shunt can be installed on back of the module as shown at left. The shunt must have 0.100 inch spacing on center and accommodate 0.25 inch pins. Example parts are Radio Shack DIP Programming Shunt #276-1512 and DIGI-Key #59000-ND. The module must be removed from the backplane to install the shunt.
