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
™ Less sound pressure (–10 dB at “operate” and –3 dB at “release” compared with EP2 / EP1)
™ For motor and solenoid reversible control
™ High performance and productivity by unique structure
™ Flux tight housing
APPLICATION
™ Power window control
™ Electrical door lock
™ Wiper system

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.
