Frequently Asked Questions (FAQ)
Q1: What causes the Fault LED on the front panel to light up?A: A steady or flashing Fault LED indicates the module has detected an abnormality and entered protection mode. Common causes include output short circuit, overload, abnormal input voltage, or internal over-temperature. First check for shorted or overloaded loads, ensure input voltage is normal, then repower the module after it has cooled down. If the fault persists, return the unit for factory repair.
Q2: Can the PSMU-350-34 be used in parallel to increase power?A: This model does not support direct paralleling. For higher power requirements, select a higher-wattage model from the same series (e.g., 500W / 900W) or a factory version designed for parallel operation.
Q3: Is high noise during operation normal?A: The built-in intelligent temperature-controlled fan runs at low speed (low noise) under light load, and increases speed (slightly higher noise) under heavy load or high temperature. Continuous sharp abnormal noise or fan stalling is abnormal; shut down the unit immediately for inspection.
Q4: Is a slightly low or high output voltage normal?A: A voltage deviation within ±1% to ±3% is normal for industrial-grade power supplies. Excessive deviation (>5%) or no output usually indicates a fault in the internal voltage regulation circuit; module replacement is recommended.
Q5: Does the module support hot swapping? What should be noted during replacement?A: Hot swapping is supported. During replacement:
- Ensure the new module has the same model and specifications as the original
- Wear an anti-static wristband
- Remove the faulty module and insert the new one quickly
- Verify normal operation by confirming the Power LED is steady and the Fault LED is off
Q6: What is the difference between PSMU-350-34 and PSMU-350-3?A: Both belong to the 350W series. The -34 is an upgraded/customized version of the -3. Main differences include number of output channels, ripple parameters, protection thresholds, or communication interfaces, while form factor and mounting remain compatible.
