GE IC200PWR102B VersaMax Expanded Power Supply

The GE IC200PWR102B, also cataloged as the IC200PWR102 Expanded Power Supply, operates as a dedicated hardware component for backplane power distribution within VersaMax system architecture platforms. It converts incoming AC mains voltage into regulated low-voltage DC rails to power CPUs, Network Interface Units (NIUs), and expansion I/O modules attached to the backplane bus.

Hardware Specifications

Backplane Bus Power Regulation and Voltage Scaling

The module delivers stabilized 5 VDC and 3.3 VDC power rails directly to the VersaMax backplane bus structure. Voltage regulation circuitry maintains tight tolerance limits across changing load demands from active I/O modules, CPUs, or communication interfaces. Internal protection networks continuously monitor for thermal overload and overcurrent conditions, executing an immediate output shutdown upon detecting a short circuit on either DC rail to protect backplane logic ICs.

Frequently Asked Questions

Q: How is the input operating voltage selected between 120 VAC and 240 VAC on this module?

A: Input voltage selection is configured via a hardware jumper installed across the two terminals located on the right side of the ground terminal. Installing the jumper configures the unit for 120 VAC nominal operation (85-132 VAC range), while removing the jumper configures it for 240 VAC nominal operation (176-264 VAC range).

Q: What happens if the combined current demand of 5 VDC and 3.3 VDC modules exceeds 1.5 A?

A: The module enforces an absolute maximum output limit of 1.5 A across both DC rails combined. Operating beyond this limit triggers internal electronic overload protection, causing output voltage collapse until the fault condition is cleared.

Q: Can this power supply module be used in a secondary or booster configuration?

A: Yes, when installed on a compatible Power Supply Booster carrier, the unit serves as a supplemental power supply to inject additional logic power into extended VersaMax backplane segments.

Field Installation Guidelines

1. Mount the module securely onto the designated VersaMax carrier backplane position. Ensure mechanical retaining latches fully engage to verify mechanical grounding.
2. Verify input jumper configuration prior to wiring AC main lines. Installing a jumper while applying 240 VAC will cause immediate power stage hardware damage.
3. Wire the incoming AC line (L1, N, FE) using 14-18 AWG copper conductors rated for minimum 75 deg C operation.
4. Bond the protective earth (PE) terminal directly to a low-impedance cabinet earth ground stud using a short, heavy-gauge conductor to ensure noise immunity and electrical safety compliance.
