GENERAL DESCRIPTION
The EFR series AC Solid State Relays are designed
to control very heavy loads. Optical isolation ensures
complete protection of control elements from load
transients. Teledyne’s advanced design featuring the
Fused CopperTM process offers users superior thermal
management resulting in superior performance,
quality and reliability.
