Description
GE IC695PSA040 Technical Specifications:
- Power Rating: 40 Watts total output capacity.
- Input Voltage (AC): 85 to 264 VAC (Nominal 120/240 VAC).
- Input Voltage (DC): 100 to 300 VDC (Nominal 125 VDC).
- Output Voltages: +3.3 VDC, +5.1 VDC, and +24 VDC Relay.
- Output Current Limits: 0-9A (3.3V), 0-6A (5.1V), 0-1.6A (24V Relay).
- Isolation: 250 VAC continuous; 1500 VAC for 1 minute (Input to Backplane).
Functional Features:
- Universal Input: Seamlessly operates on both standard AC mains and high-voltage DC control power.
- Comprehensive LED Diagnostics: Features four distinct status LEDs: Power (Green/Amber), Power Supply Fault (Red), Over Temperature (Amber), and Overload (Amber).
- Electronic Protection: Built-in overcurrent protection on the 5.1V and 3.3V outputs. The power supply automatically shuts down and attempts to restart once the overload condition is cleared.
- Safe Operation: Includes a front-panel On/Off switch located behind a protective door to prevent accidental power cycling.
Application Scenarios:
- Primary power source for small to medium-sized PACSystems RX3i control racks.
- Industrial environments with fluctuating AC line voltages or DC battery backup systems.
- General-purpose machine control and process automation panels.
Performance Parameters:
- Slot Occupancy: Requires two (2) consecutive slots in the RX3i universal backplane.
- Wiring Capacity: Accepts 14 AWG to 22 AWG solid or stranded wire (one wire per terminal).
- Environmental Limits: Operating temperature from 0°C to 60°C; Storage temperature from -40°C to +85°C.
- Humidity Tolerance: 5% to 95% non-condensing.
Material Composition & Structural Characteristics:
- Enclosure: Heavy-duty metallic and industrial plastic composite housing with an integrated safety door.
- Terminals: High-current screw terminals for secure AC/DC input and chassis grounding.
- Internal Components: High-efficiency switching power supply components with internal backup fusing for overcurrent protection.
Working Principle: The module converts incoming AC or DC power into three isolated DC voltage rails. The +3.3V and +5.1V rails power the internal logic and backplane communication, while the +24V relay output provides power for discrete output modules. Continuous internal monitoring circuits check for voltage anomalies, thermal limits, and current draw, triggering protective shutdowns if parameters exceed safe thresholds.
Installation Requirements:
- Single Installation: Only one IC695PSA040 power supply can be installed per universal backplane. It does not support parallel load sharing or redundancy with other RX3i power supplies.
- Grounding: A dedicated chassis ground connection is mandatory for EMI compliance and safety.
- Torque: Tighten input terminal screws to manufacturer specifications to prevent arcing and heat buildup.
Usage Precautions:
- Safety Hazard: Always keep the front door closed during operation to prevent fatal electric shock.
- Internal Fuse: Contains a non-replaceable internal fuse. If the fuse blows due to an internal fault, the entire power supply module must be replaced.
- Door Interlock: Never operate the module with the safety door removed or open.
- LED Troubleshooting: If the red Fault LED illuminates, consult the CPU fault table for specific diagnostic codes before replacing the unit.
