AUTOMOTIVE RELAYS
EP2S/EP1S SERIES
LOW SOUND PRESSURE
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
