DATA SHEET
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
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.
