Model: ES-1.5K

Failure phenomenon: 2 no output, one did not show.

Fault analysis: the customer is Hong Jia Wei long-term cooperation and old customers for plastic factory is mainly plastic blow molding, bag, bag cutting device with frequency converter, film blowing machine, bag making machine, bag cutting machine, plastic machine, slitting machine, laminating machine, printing machine. Frequency converter for a lot of customer equipment, mostly imported brand inverter. Repair for Sanken inverter inverter. There are two sets of measured IGBT modules to bad. One is not displayed. Analysis for the output short circuit caused by the combined use of the environment led to the use of the site. The module is broken down to the normal power supply. Run measurement drive voltage is also normal. Replace the module after the normal operation of the power. No display of measured power supply DC bus voltage is normal. Switching power supply without vibration. Replace the power IC after the failure is still. Inference may be caused by a short circuit after the measurement of 5V power output static resistance value of 13 ohm, to determine the short circuit. After one by one to find out the capacitor to short-circuit. After the replacement of all normal.

Fault repair: replacement module and power supply IC, capacitor.

No phase display, Sanken inverter, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, output module, display without damage, fault code, Hong Jia Wei can repair.
