Custom SSR’s available. Contact us for your application.

The Dual SSR data sheets are still in work.  Contact us for more infomation.

 

Part number format: SSR-BBBBBCA-XXV-XXC where

SSR = Solid State Relay designation
BBBBB = the base part number
CA, Blank or CA = Common Anode, CC= Common Cathode, N = Phase Leg
XXV = Voltage rating designation, i.e. 30V, 60V, 100V.

xxVL = switches Low side only when used without an HSC512TTL

XXC = Control Voltage designation, i.e. 5V, 12V, 24V
