- Input Full-range Test: Apply 85 V AC, 120 V AC, 264 V AC, 120 V DC and 300 V DC input voltages respectively, confirm output voltage stays within ±1% of rated value under all conditions.
- Load Characteristic Test: Run 0% to 110% full load step test, verify output voltage stability and ripple noise level meet published specifications at every load point.
- Redundancy Parallel Test: Connect two identical modules in parallel, confirm automatic load sharing function works correctly, no overcurrent or output conflict occurs during hot-swap of one unit.
- 72-hour Full Load Burn-in Test: Operate the module under 55 °C ambient temperature with 100% rated load, continuously log output voltage, current and temperature data, no overheating or abnormal shutdown is allowed during the whole period.
- Dielectric Withstand Test: Apply 2000 V AC isolation voltage between input, output and chassis ground for 60 seconds, confirm no breakdown or leakage current exceeds 1 mA.
- Final Performance Audit: Generate full test report, attach traceable calibration label and release the unit with 12-month formal quality warranty.
Installation Guide
- Pre-installation Preparation: Confirm the module is installed in the dedicated power slot at the far left of the 3500 rack, wear anti-static wrist strap before handling, verify input power type and voltage match the module specification.
- Module Insertion: Align the full-height module with the rack guide rails, push it smoothly inward until the backplane connector is fully seated, tighten the two front panel mounting screws to secure the unit.
- Input Power Wiring: Connect the AC/DC input power cable to the corresponding terminal on 106M1081-01, use 14 AWG or thicker power cable, add external fuse protection at the input side as required by site electrical safety standards.
- Redundancy Configuration (if applicable): For 1+1 redundant setup, connect two independent input power sources from separate UPS systems to the two power modules, enable automatic load sharing function via 3500 configuration software.
- Power-on Validation: Apply input power gradually, confirm the front panel power status LED turns solid green, measure output voltage to confirm it meets rated specification, then power on all other 3500 rack modules and verify full system startup completes normally.
