Single Phase Solid State Relay

Single Phase Solid State Relays – SVDA SVAA

Product Description

Single Phase Solid State Relay


The current ratings of the SV range are 10, 25, 50 and 75 amps for 300 volt rating. 50 and 75amps for 600 volt rating. Incorporates Superior Surge Survival™ providing increased immunity to voltage transients.


The SV Series accepts DC Logic inputs (SVDA) or AC Logic inputs (SVAA).

Firing mode

All units are Logic fired with zero voltage switching.


External high speed fuses and fuseholders can be used.


These units are designed to be mounted on panel walls (metallic) or other heatsink in order to keep the base temperature below 40°C.
