DESCRIPTION

The NEC TOKIN EP2 / EP1 series are PC-board mount type automotive relays suitable for various motor

controls and other applications that require a high level of quality and performance.

EP2 series is a twin-relay and divided into two types for different usage.

One is an H-bridge type designed for forward and reverse control of the motors, and the other, a separate

type containing two separated relays in one package.

EP1 series is a 1 Form c relay equivalent to EP2 series in performance.

FEATURES

For motor reversible control and solenoid control

Approx. 50% less relay space than conventional relay

High performance and productivity by unique structure

Flux tight housing

APPLICATIONS

Power window

Antenna lifter

Auto-seat positioning

Electrical door lock

Passive seat belt control

Keyless/Remote entry system

Sliding roof control

NUMBERING SYSTEM

TYPICAL APPLICATION (H Bridge Type)

MOTOR Tr1

Tr2 STOP off off FORWARD on off REVERSE off on

It is necessary to take more than 100 ms intervals for on / off timing between driving Tr1 and Tr2. If the interval is less than 100 ms, an excessive current happen to flow to the relay contacts.
