IC698PSA100 GE FANUC RX7i Power Supply Module

IC698PSA100 Power Supply Module

General Description

The RX7i power supplies provide 5V, 12V, and -12V power, along with the VME AC_FAIL# logic level signal to modules on the RX7i backplane. The IC698PSA100 delivers up to 100W total output at ambient temperatures of 0 to 60ºC without forced air cooling.

Features

• Operation Voltage: 85 to 264 VAC, 100-150 VDC
• Output Voltages:
  • +5 VDC output up to 20 amps
  • +12 VDC output up to 2 amps
  • –12 VDC output up to 1 amp
• Construction: Slide-in rack mount using PICMG 2.11 standard connector
• Protection: Overcurrent, overvoltage, and overtemperature protection
• Power Factor Correction: For AC operation

Specifications

Indicators

• FIELD OK (Green): Turns ON when AC power is within specification.
• OUTPUT OK (Green): Turns ON when all DC outputs are within specifications.
• OVER TEMP (Red, IC698PSA350 only): Turns ON if critical supply temperature is exceeded or airflow ceases.

Protection Features

• Overvoltage: Exceeding nominal output voltage by 15% or more will cause outputs to latch off.
• Overcurrent/Short Circuit: All outputs are protected with automatic recovery upon fault removal.
• Temperature and Air Flow: Internal temperature sensing shuts down outputs when overheated. Airflow sensor detects fan failure or air blockage.

Installation

• Slot Position: Leftmost slot of any standard RX7i rack.
• Wiring Connections: Use copper AWG #16 wire rated for 75°C (167°F) for input power connections.

System Noise Immunity

• Proper grounding of the PLC system is essential to reduce errors due to electrical noise. Connect the GND terminal on the power supply to the GND terminal on the rack and to earth using copper AWG #12 wire.
