Selection Guide
Use the following criteria to confirm the GE 8920-PS-DC-02 is the right power supply for your application:
- Step 1 – Input Voltage: Confirm your panel supplies DC voltage matching the module’s rated input range
- Step 2 – Load Calculation: Sum the current draw of all modules in the rack; ensure the power supply output capacity is sufficient
- Step 3 – Rack Slot: Verify the power supply occupies the designated slot (typically slot 0 or slot 1) in your rack model
- Step 4 – Environment: Confirm ambient temperature, humidity, and vibration ratings meet your installation conditions
- Step 5 – Redundancy: For critical applications, evaluate whether a redundant power supply configuration is required

Replacement & Compatibility FAQ
Q: Is the GE 8920-PS-DC-02 still in production?
A: This model may be discontinued. Konmask.com maintains surplus stock and can source equivalents. Contact us for current availability.
Q: Can I replace the 8920-PS-DC-02 with an AC input power supply?
A: Only if your panel wiring is modified to supply the correct AC input voltage. The AC variant (8920-PS-AC-01) is not a drop-in replacement without rewiring.
Q: Will a third-party power supply work in a GE Series 90-30 rack?
A: Some third-party units are compatible, but GE diagnostics and fault codes may not function correctly. We recommend OEM or verified equivalents.
Q: What is the lead time for the GE 8920-PS-DC-02?
A: Typically 3–7 business days for in-stock units; 2–4 weeks for sourced/surplus units. Contact us for real-time availability.
Q: Do you provide a warranty?
A: Yes — all units carry a 12-month replacement warranty. See our warranty policy for details.
