SSR Unit

UNIT SSR Solid-state relays are different from traditional electromagnetic relays in that their switching life are much longer than that of electromagnetic relays. With integrated MOC3043M optocoupler isolation and zero-crossing detection,It supports input 3.3-5V DC control signal, and control output single-phase 220-250V AC power.

Support the following products:
