OMEGA's SSR330 and SSR660 Series solid state relays are single-pole, normally open switching devices with no moving parts, designed for AC load switching at zero voltage crossover to minimize electrical noise. Both DC and AC input control models are available, with line voltage ratings of 330 Vac or 660 Vac and load current ratings from 10 A to 75 A. The relays feature optical isolation, an LED status indicator, built-in snubber, and require mounting on a finned heat sink for thermal management. Dimensions are 47.6 mm × 27.9 mm × 4.8 mm (1.875 in × 1.10 in × 0.19 in), with mounting holes accommodating 8-32 and 4-40 threads. The series includes models with 24 to 330 Vac or 24 to 660 Vac operating ranges and control signal voltages of 4 to 32 Vdc or 100 to 280 Vac.
OMEGA's SSR330 & SSR660 Series Solid State Relays (SSR) are single-pole, normally open switching devices with no moving parts, capable of millions of cycles of operation. By applying a control signal, the SSR switches ON the ac load current, just as moving contacts do on a mechanical contactor.
Switching takes place at the zero voltage crossover point of the alternating current cycle. Because of this, no appreciable noise is generated. Both dc and ac input control signal models are available.
