Application

The coil of the DC reversing contactor produced by the DC contactor supplier uses DC power supply, mainly used in the EPS power supply of the communication base station, and the contacts can also be used for AC loads of 380V, 220V and 110V.

The DC reversing contactors of DC contactor suppliers are compact in design and stable in structure, and can work stably in various harsh environments to ensure reliable power supply and safe operation of communication equipment.

Experienced DC contactor suppliers ensure that communication equipment can be switched to backup power in a timely manner in the event of a power outage or emergency, ensuring the continued and stable operation of the communication system.
