ASR-SI Single-Phase AC Output Solid-State Relays

Altran Magnetics ASR-SI Single-Phase AC Output Solid-State Relays (SSRs) feature zero switching or random-on switching and current ratings from 25A to 125A at 48V_AC to 660V_AC. The Altran Magnetics ASR-SI series offers 4000V_ACrms dielectric strength and an SCR or a TRIAC output. These single-phase AC output SSRs provide DC input, LED indication, and an optional internal MOV/TVS protection circuit.
