Application
Latching DC Contactor is compact in design, has fast response and reliable holding characteristics, and can achieve low power consumption and high efficiency control.
Latching DC contactors are mainly used to control switching on/off of power supply of storage battery car, electric forklift, electric winch, electric car, excavator, air conditioner in vehicle.
Latching DC contactors are widely used in new energy vehicles, power tools, solar photovoltaic systems, battery management systems, industrial automation and other fields.
