EP2S/EP1S SERIES
AUTOMOTIVE RELAYS
LOW SOUND PRESSURE
Document No. ER0131EJ1V0DS00
Date Published April 1996 M
Printed in Japan

DESCRIPTION
The NEC EP2S / EP1S 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 sound pressure level of EP2S / EP1S series is 57 dBA nominal when the relay operates, and 49 dBA
nominal when the relay releases.
FEATURES
TM Less sound pressure (10 dB at "operate" and 3 dB at "release" compared with EP2 / EP1)
TM For motor and solenoid reversible control
TM High performance and productivity by unique structure
TM Flux tight housing
APPLICATION
TM Power window control
TM Electrical door lock
TM Wiper system
