Selection Guide
Use the following criteria to confirm the 900P01-0501 is the correct module for your application:
- Step 1 — Identify your cabinet type: Confirm HPM, APM, or LM cabinet; check existing power module label for part number
- Step 2 — Verify input voltage: Confirm your cabinet power bus supplies 24V DC to the power module slot
- Step 3 — Check revision suffix: The suffix -0501 denotes a specific hardware revision; earlier revisions (-0101, -0301) may be interchangeable — consult Honeywell documentation or contact us
- Step 4 — Redundancy requirement: If running redundant power, confirm you need a matching second unit (900P01-0501 × 2)
- Step 5 — Contact Konmask: Send us your cabinet model, existing part number, and system software version for a free compatibility confirmation
