How to solve the undervoltage of Mitsubishi elevator main circuit

Replace the power board and check the running status of the elevator.

1. According to the elevator recruitment website, replace the power board: the power board is normal and the voltage is still low, so it is necessary to replace the main circuit power board.

2. Check the running state of the elevator: If the elevator suddenly stops during operation, it is necessary to check whether the emergency stop and door lock loop are abnormal.
