Description
Product Introduction & Engineering Value
Power supply failures rarely provide much warning. An unstable DC bus can produce communication faults, unexpected CPU resets, or intermittent I/O errors that resemble controller failures. The GE IC698PSA100 is the foundation of every PACSystems RX7i rack, delivering regulated power to CPUs, communication modules, and I/O assemblies.
Designed for continuous industrial operation, the IC698PSA100 accepts a wide AC or DC input range, includes power factor correction, and provides built-in protection against overcurrent, overvoltage, and overtemperature conditions. Its slide-in construction also simplifies maintenance during scheduled outages.

Field Application & The “Trench” Experience
A municipal water treatment facility began experiencing random controller resets after brief utility voltage disturbances. Initial troubleshooting focused on the CPU and Ethernet network, but no hardware faults were identified.
Engineers eventually discovered that the aging rack power supply no longer maintained output during short input voltage interruptions. Replacing the IC698PSA100 restored stable operation without changing the CPU, I/O modules, or application software. The system completed several subsequent power quality events without interruption.
Typical application scenarios include:
- Combined-cycle power plant auxiliary control racks
- Water treatment PLC cabinets with distributed I/O
- Automotive body shop production lines
- Continuous chemical processing systems
- Material handling and warehouse automation systems

The Veteran’s Tech Trap Guide
⚠️ Calculate the Rack Power Budget First
The IC698PSA100 provides 100 W total output. Before replacing or expanding an RX7i system, calculate the cumulative current requirements of every installed CPU, communication module, and I/O card. Exceeding the available power budget can lead to intermittent startup failures.
⚠️ Don’t Confuse It with the 350 W Version
The and IC698PSA350 are mechanically similar but have significantly different output capacities. Installing the lower-capacity supply in a heavily populated rack may result in unstable system operation.
PRO TIP:
If an RX7i CPU repeatedly resets after adding new modules, measure the power supply loading before replacing the processor. In many installations, the issue is insufficient power capacity rather than a defective CPU.
⚠️ Remember the Front Switch Is Not an Isolation Device
The front-panel ON/OFF switch controls the power supply outputs but does not disconnect the incoming AC line. Hazardous voltages remain present inside the module whenever the input source is connected. Follow proper lockout/tagout procedures before servicing.
Dynamic FAQ
Q1. What is the primary function of the ?
The supplies regulated +5 VDC, +12 VDC, and –12 VDC power to the PACSystems RX7i backplane while also generating the logic-level power sequencing signals required by rack modules.
Q2. What input voltage does the power supply support?
The module operates from 85–264 VAC (47–63 Hz) or 100–150 VDC, making it suitable for a wide variety of industrial power systems.
Q3. Does the require a fan tray?
No. Unlike the higher-capacity IC698PSA350, the can deliver its full 100 W output over an ambient temperature range of 0°C to 60°C without forced-air cooling.
Q4. Is New Surplus inventory genuine?
Yes. New Surplus modules are authentic OEM inventory that has never been installed in production equipment. Each unit is inspected for identification, connector condition, and physical integrity before shipment.
Q5. How are refurbished power supplies tested?
Every refurbished unit undergoes AC/DC input verification, output voltage regulation testing, load testing across all output rails, protection circuit verification, thermal burn-in, and final functional inspection before shipment.
Q6. Where is the installed?
The installs exclusively in the dedicated power supply slot (Slot 0) on a PACSystems RX7i main rack and provides operating power to all compatible CPUs, communication modules, and I/O modules installed in that rack.
