General Description: The NCC Series of
Solid State Power Relays provide a highly reliable means of switching a variety of AC
loads up to 40 Amps. Snubber circuitry is included with each unit for high dv/dt
applications and inductive loads.
Use of rugged output devices provides significant increases in turn-on surge capability.
Two input control voltage ranges are available in either Form A (SPST-NO) or Form B
(SPST-NC) output configurations.
