SOLID STATE RELAYS

Solid State Power Relays

Model R2025

FEATURES

CSA certified file #LR701222

100% functionally and surge tested

24 to 330 VAC load voltage

4000 V isolation

Optically coupled

Epoxy filled

Capable of being switched by a single

CMOS gate

Built in snubber

Capable of switching inductive loads of

0.5 power factor

UL recognized component file

#E164906

The AMETEK NCC Series of Solid State

Power Relays provide a highly reliable

means of switching a variety of AC loads up

to 20 A. 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 capa-

bility. Two input control voltage ranges are

available in either Form A (SPST-NO) or

Form B (SPST-NC) output configurations.
