Superior Internal Snubber Circuit 
The SV Series attenuates most industrial noise for higher reliability and less down time. By having higher a Dv/Dt and higher “blocking voltage” ratings the SV model is more rugged than the competition. Most relays have a 600 VAC blocking voltage. Using an external MOV (at 700 volts) offers no protection to most solid state relays, which will fail when subjected to voltage spikes. The SV model is 33% better (800 volts) so an external MOV is well below the range of the SSR.
 

Superior AC Input Circuit 
By improving the leakage immunity of the input circuit, “triac” instruments that use a 0.022 microfared snubber no longer require an external burden resistor across the input circuit, thus reducing cost and installation time. Most AC activated relays have a turn-on and turn-off delay built in. When used as high-speed pulsing control (such as with temperature controllers), other SSR’s response can be irregular for the first 16% and last 16% of the duty cycle. This error may impact start up control, overshoot control, and other parts of the control operation. The new SV relays provide linear response so you receive predictable control from 1-100% output in your application.

Applications 
The SV Series provides an effective replacement for electromechanical contactors. The fast switching reduces the thermal cycling of the heating elements resulting in longer element life. There are no mechanical contacts to wear out and so maintenance costs and downtime are reduced.
