YM Tech’s EV Relay consists of various current rating such as DC 450Voltage class 10 A, 30 A, 50A 100A,150A, 250A, 400A, 600A.

EVR10 and EVR30 Relay are used for pre-charge devices,

EVR50 Relay is used to the heating system in the electric vehicles.

EVR100 and EVR150 Relay are used as the main Relay of electric hybrid vehicles, and

EVR250, EVR400 and EVR600 Relay are used as the main relay of electric buses, pure electric vehicles. 

EVR50 ~ EVR400 Relay is used for DC750V for the rapidity charging systems.

YM Tech's EV relay received CCC certification for the first time in the world and acquired IEC CB, CE, UL, etc., thereby complying with all international standards.

  There are 6 features of YM Tech's EV relay

   1. Less noise during operation

   2. various voltage of coil

   3. Built-in auxiliary contacts

   4. PMW energy-saving devices(economizer)

   5. DC1000V High Voltage EV Relay

   6. DC Bidirectional Switching Relay

Since the movable core stops by plastic resin, the noise is reduced during operation below 60 db. So YM Tech’s EV Relay is suitable for electric vehicles, electric hybrid vehicles, etc.

Furthermore, YM Tech's EV Relays have various coil voltage ranges from DC12V to DC220V.

YM Tech EVR100 to EVR600 has auxiliary contacts which helps monitor main contact's state of EV Relay and transmits the main contact's to the CPU of charging facilities.

PWM energy-saving unit supplies inrush current for pick-up and maintains a holding current after completing pick-up operation. PWM unit minimizes the energy consumption of the coil.

YM tech have completed 100 ampere EV relay and 200 ampere EV relay at DC 1000 voltages. 1000V class EV Relay used in the energy storage system and the solar inverter.

With its unique technology, YM Tech has developed EVHB500 Relay which cuts off DC1000V 400A regardless of the current direction. it's named bi-diection EVrelay.

When the batteries of energy storage system function to charge and discharge, the current direction is changed. At this time, YM Tech have developed first DC 1000V class bi-directional EV Relay in the world. EVHB500 safely cuts off the current flowing through main contact in the opposite direction.
