The Frequency Converter And Its Operating Environment Need To Be Inspected Regularly.

Monitor the operating status of unit 480v 60hz to 380v 50hz converter. Read output voltage, current, and frequency values ​​from the panel. Compare the balance of three-phase output voltage and current. Use a thermometer to measure the casing temperature to determine if there is an overheating trend or abnormal temperature rise, and pay attention to any unusual odors or sounds.

Check the power input and control circuit. Confirm that the input AC voltage is within the specified range to prevent damage to components caused by exceeding the rated voltage. Check all connecting bolts and terminals for looseness, oxidation, or detachment. Check that the control terminals are secure and that the grounding and insulation are up to standard.

Periodically clean and inspect critical internal components. Clean the air filter, radiator, and cooling ducts. Remove dust, oil, and corrosive substances from inside unit frequency converter 60hz to 50hz 3 phase and the cabinet. Check the busbars, busbars, connectors, and capacitor casings for deformation, corrosion, or signs of aging; replace aged parts if necessary.
