Question
Can an Inverter be operated and stopped using a magnetic contactor (MC)?
Answer
An Inverter can be operated and stopped by using a magnetic contactor (MC) on the primary side, but for the following reasons, do not turn the power supply ON and OFF frequently.
1.If the power supply is turned ON again before the inrush current prevention resistor cools, built-up heat will burn the resistor (abnormal resistor heat).
2.The service life of the relay that short-circuits the inrush current prevention resistor will be shortened.
3.The service life of the capacitor for the power supply section will be shortened.
A limit of once every 30 minutes is recommended for turning the power supply ON and OFF.
