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 EP2S SERIES EP1S SERIES

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.
