Jiangsu Nantong Yancheng Huaian Xuzhou Lianyungang ABB inverter fault repair

Nantong Yancheng Huaian Xuzhou Lianyungang BB inverter touch screen professional maintenance center provides free testing and the lowest fee. BB inverter should be an earlier brand to enter the Chinese market, so some old products like BB inverter are still used by a large number of users. Let’s first analyze the common faults of these two series of products. . Black body welcomes consultation -

The most common fault we have with BB inverters is that there is no display when power is turned on. The switching power supply of this series of inverters uses a chip as a waveform generator. , the damage of the chip will cause the switching power supply to be unable to work, and thus the display will not be normal. In addition, the abnormal working power supply of the chip will also cause the switching power supply to be unable to work normally.
Our more common faults with BB inverters mainly include damage to the drive circuit and damage to the B module. The drive circuit is driven by a pair of tubes to drive the B module, and this pair of tubes is also the most easily damaged component. , the cause of damage is often due to damage to the B module, which causes high voltage and large current to flow into the drive circuit, causing damage to the components of the drive circuit.
BB inverter, we often encounter fault phenomena such as (low DC voltage). Since the sampling signal is obtained directly through the resistor step-down, the fault is mainly caused by the damage of the sampling resistor.
BB inverter, regarding the input phase missing alarm, the first reason for the failure is that the series itself has an input phase detection function. Damage to the input detection circuit will cause an input phase missing alarm. If the cause of the fault is eliminated, the alarm signal will still be there. If it cannot be eliminated, the fault is most likely caused by damage to the board.
