Holip frequency converter maintenance
Model: HPL-A0.75KW
Failure phenomenon: no display on the power
Failure analysis: customers take over 4 inverter has 3 units are the same fault on the power of the power supply is not shown but the main power supply light. The other one is the IGBT module to display burn. Open the inverter power supply drive plate has a shell that driver a burnt traces. This optocoupler remove measurement in the short circuit, IGBT module for good measure. The replacement of the new power PC923 optocoupler drive voltage is measured after normal. Running frequency converter measurement output all normal. With load test current is normal. Fault repair. This fault is the driving power supply voltage is too high or lead to bad heat burn lead to short-circuit power from the optocoupler protection caused by such failure.
Hong Jia Wei maintenance can solve the common vector HLP-A100 converter and HLP-B converter of high performance vector type, HLP-NV type, HLP-C100 inverter inverter vector vector type inverter HLP-A Mini universal special HLP-SK100 inverter, high performance air compressor air compressor HLP-SK110 special frequency converter vector, HLP-SK180 converter, HLP-SL100 converter for permanent magnet synchronous lifting the special HLP-P inverter, dedicated fan pump, HLP-H converter, HLP-M inverter frequency machine special machine tool special holip frequency converter fault: no display, lack of phase, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, output module, display without damage.
Holip frequency converter, display phase, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, output module, display without damage, fault code, Hong Jia Wei can repair.
