How to troubleshoot excessive DC output voltage ripple on ZTE ZXD3000 (V5.0)?

Disconnect module output, measure electrolytic filter capacitor ESR, inspect current-share busbar contact resistance for oxidation, and verify PWM switching clock synchronization.

What is the diagnostic procedure when ZTE ZXD3000 (V5.0) triggers AC input undervoltage lockout in unstable grids?

Monitor RMS line voltage with a power analyzer to verify dips below the 85VAC threshold; widen the undervoltage recovery hysteresis by 5V in the controller to prevent cycling.

What are the root causes of multi-unit current-sharing imbalance (deviation > 10%) on ZTE ZXD3000 (V5.0)?

1. Open current-share bus wire or oxidized backplane connector pins. 2. Zero-drift on module internal voltage calibration pot. 3. Asymmetrical branch cabling impedance; reseat units and re-calibrate no-load voltage baseline.
