The SSP1A125BDT is a panel-mount, single-phase solid state relay from the Harmony Solid State Relays range, designed for zero voltage switching of AC loads. It operates with a control circuit voltage of 3 to 32V DC and switches a load current from 0.15A to 25A across an output voltage range of 24 to 300V AC. Key features include an SCR output, a low on-state voltage drop of less than 1.15V, a high off-state dv/dt of 500 V/µs, and a green LED input status indicator. This relay is suitable for motor control applications with ratings up to 1 hp at 240V AC, and its robust design with 4 kV AC dielectric strength ensures operational safety and reliability.
