Lamp Loads Zero voltage switching is ideal for driving incandescent lamps, since the cold filament will not be subjected to a large inrush current. UL Motor Load Ratings (HP Ratings) Part Number Read the technical notes on the following page prior to installing solid state relays. RSS series relays provide a highly reliable means of switching AC loads when applied properly.
RSS relays use high-noise immunity circuitry with a built-in snubber to handle the electrical noise generated by inductive loads. In such cases, use an SSR relay at no more than 75% of the rating. Heater Loads When using solid state relays for driving heaters where the load is switched on and off rapidly and continuously, severe thermal stress will result. Use a relay rated for this surge, which has a 1/2 cycle surge current greater than the maximum applied line voltage the transformer’s primary resistance (approximately 10x rated current). Recommended Loads Transformer Loads Transformer loads sometimes result in severe inrush current when the transformer saturates during the first cycle.
