CW-390/CW-391/CW-392

ELECTRONIC HIGH CURRENT RELAYS

The series of electronic high current relays (CW-390, CW-391 and CW-392) are an efficient and economic replacement for conventional electromechanical relays.

The semiconductor technology used (power MOSFET) and the rugged design of the series ensures there are no contact sparks nor contact erosion or any other kind of interference.

The CW-390 is an electronic relay designed to switch direct current loads of maximum 35 A. In contrast to the CW-390 the CW-391 requires a separate power supply and is able to switch loads up to 70 A. The power, control and load connections are galvanically isolated from one another. The CW-392 is an electronic relay designed to switch direct current loads of maximum 70 A; it has an integrated current measurement function, whose data can be retrieved per CAN bus. In addition, it is possible to control its switching behaviour with CAN commands.

It is also possible to adapt the electronic high current relays to suit your requirements. Please do not hesitate to contact us!
