The "hockey puck" style RSS series of solid state relays allow switching of the most demanding loads. Highly resistant to inrushes, with a built-in snubber, the RSS series is ideal for switching loads such as lights and heaters. Available with either DC (4-32V) or AC (90-280V) inputs with output current ratings up to 90A. All models feature zero-voltage turn-on to reduce inrush current and a dual SCR switch (rather than a triac) for enhanced reliability and superior heat dissipation properties.
