EP2 Series Data

Features

The NEC EP2 series relay is similar to the EN2 series but smaller. The EP2 is a PC-mount, fully-sealed, high-density dual relay. The EP2 consists of two 1 Form C (SPDT) relays in one unit.

The EP2 is available with interconnections for H-bridge motor drive, or with no interconnects for independent operation. The EP2 is intended for automotive loads up to 25A, and is offered with a high temperature option (125° C ambient), or as a quiet type.

  • Twin relay for reversible motor control
  • 50% less relay space than 2 conventional relays
  • High performance & productivity by unique symmetrical structure
  • Flux tight housing
