Relay RE20-48
48 VDC Coil

Product Use

This Relay with 48VDC Coil is especially developed for Automotive use as servo switch in Electric Vehicles (EV).

Low current (Typically 40 to 50 milliAmperes) through the Relay Coil electromechanically switches ON a High current Load (up to 30A).

In constant ON applications it can carry up to 30 Amperes, while in pulsed applications up to 20 Amperes may be switched momentarily.

Thousands of these devices have been reliably used since 2003 in following applications:
