Configured for primary or booster backplane power delivery in VersaMax systems, the GE IC200PWR002 (IC200PWR002 Power Supply Module) provides direct physical/electrical execution. Operating within an input voltage range of 18 to 30 VDC (24 VDC nominal), the unit converts input power to generate dual regulated output buses of 5 VDC and 3.3 VDC. The module delivers a maximum total output current of 1.5 A across both buses (up to 1.0 A at 3.3 VDC and up to 1.5 A minus 3.3 V power consumption at 5 VDC) to power backplane logic for CPUs, Network Interface Units (NIUs), and I/O expansion racks.

Deterministic Network Backplane Power Integrity & I/O Scaling
The IC200PWR002 enforces stable power delivery across the VersaMax backplane bus, maintaining consistent logic voltage thresholds required for Profinet and EtherNet/IP deterministic networks. By accommodating extended power demands, the supply prevents voltage droop on CPU and NIU drops during peak I/O density scaling. Integrated hardware protection circuits preserve firmware flash compatibility during live load fluctuations, suppressing power-induced bus dropouts and maintaining lockstep communication execution.
Frequently Asked Questions
Q: What is the primary difference between using the IC200PWR002 on a CPU/NIU base versus a booster carrier?
A: When mounted on a CPU or NIU base, the IC200PWR002 functions as the primary power supply for the main rack. When installed on a power supply booster carrier, it operates as a secondary supplemental power supply to expand downstream I/O backplane capability.
Q: How are the front-panel screw terminals wired for power input?
A: The bottom front panel features 5 screw-type terminals: the two left-most terminals are assigned to +DC and -DC input power, the 3rd terminal connects to frame ground (earth), and the final two terminals require no connection.
Q: Does the IC200PWR002 include integrated isolation between input and output power circuits?
A: No. The IC200PWR002 does not feature isolated power output circuitry. External field power isolation must be maintained upstream if galvanic isolation between field DC power and logic ground is required.
Field Installation Guidelines
-
Safety Isolation: Ensure all main 24 VDC supply sources are switched off prior to mounting, removing, or terminating wiring to the power supply module.
-
Terminal Wiring: Connect the 24 VDC input power leads to the designated +DC and -DC screw terminals on the bottom front panel. Tighten terminal connections to recommended industrial torque standards.
-
Grounding: Wire the 3rd terminal on the bottom terminal block directly to functional protective earth (PE) ground to ensure proper surge clamping and noise immunity.
-
Mechanical Mounting: Align the module housing over the primary baseplate or booster carrier guide channels and push firmly until the locking tab snaps into position.
- Inrush Protection: Verify that upstream DC power sources and fusing can sustain an inrush current pulse of up to 25 A for 6 ms during cold startup without tripping.
