The electric vehicle DC contactor adopts a modular design, which can assemble the number of contacts required by the customer and the contact form (normally open, normally closed and conversion) required by the customer with the fewest parts; the contact of this series of products is broken The voltage is high, and the cross-blowing magnetic field is used to extinguish the arc, and the highest breaking voltage can reach 220VDC. The product is suitable for program-controlled power supply or uninterruptible power supply system, forklift, electric vehicle, and construction machinery system.
Application
The products are mainly used in the power supply on and off control of de power systems
such as battery cars, electric forklifts, electric winches, electric cars, excavators, automobile
air conditioners and communication power supplies.
