Zero Crossing, also known as burst mode firing are used with resistant elements such as and , but can not be used with inductive loads like a transformer or with fast changing elements like lamps and moly elements.
Use any controller like Watlow and Omega to control your SCR
Our SCR is a direct replacement for any other make SCR, like Omega, Watlow, Johnson and Chromolox
This SCR controls all three hot legs.
