The GE IC200PWR101, also cataloged as the IC200PWR101 AC Power Supply Module, operates as a dedicated hardware component for backplane logic power distribution within VersaMax PLC platforms. Receiving an alternating current input of 120/240 VAC (47 to 63 Hz), the unit converts incoming mains power to supply regulated backplane logic rails of 5 VDC and 3.3 VDC with a maximum total combined output of 1.5 A. Featuring a holdup time of 20 ms and built-in protection against short circuits and overloads, the module directly powers CPUs, Network Interface Units (NIUs), and I/O modules across the backplane bus.

Deterministic Network Backplane Communication & Power Integrity
The IC200PWR101 maintains constant backplane bus communication velocity by supplying stable logic power to local CPUs and NIU network drops. Stable output rail regulation prevents logic resets during line voltage sags, supporting deterministic Profinet or EtherNet/IP transactions across extended I/O density configurations. Integrated overcurrent circuitry safeguards system firmware flash operations by suppressing power transients during AC supply switching.
Frequently Asked Questions
Q: How is the input voltage range (120 VAC vs. 240 VAC) selected on the IC200PWR101?
A: Input voltage selection is configured via hardware jumper positions on the module base prior to applying primary AC mains power.
Q: What is the maximum allowable current draw on the 5 VDC backplane rail?
A: The maximum current on the 5 VDC rail is 1.5 A minus whatever current is actively drawn by 3.3 VDC loads (up to a 0.25 A limit on the 3.3 VDC rail). The total output current across both rails must not exceed 1.5 A.
Q: Can the IC200PWR101 be used as a supplemental power supply on a booster carrier?
A: Yes. The IC200PWR101 can serve as a primary power source when mounted to a CPU/NIU base, or as a supplemental power source when installed on a power supply booster carrier in expansion racks.
Field Installation Guidelines
-
Power Isolation: De-energize all primary 120/240 VAC supply lines before installing, removing, or wiring the module to avoid electrical shock hazards.
-
Jumper Configuration: Verify the input voltage jumper position matches the field supply voltage (120 VAC or 240 VAC) before applying power.
-
Grounding: Wire the dedicated AC protective earth (PE) terminal securely to the cabinet ground bar to ensure proper surge suppression and EMC compliance.
-
Physical Installation: Align the module with the guide channels on the VersaMax baseplate or booster carrier and press firmly until the retaining clip locks into position.
- Thermal Management: Ensure vertical ventilation space around the module remains unobstructed to maintain passive cooling across the operating range.
