DESCRIPTION

The NEC EP2F / EP1F 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. The operate temperature range for EP2F / EP1F series is –40˚C through +125˚C. By this high heat resistivity, the contact carrying current of EP2F / EP1F series at 25˚C increases 1.3 or 1.4 times compared with that of EP2 / EP1 series.

FEATURES

ª Operating ambient temperature up to +125˚C (EP2 / EP1 : +85˚C) ª Suitable for motor and solenoid reversible control ª High performance and productivity by unique structure ª Flux tight housing

APPLICATIONS

ª Power window control ª Power sunroof ª Wiper system EP2F SERIES EP1F SERIES

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