Model 7300A is a rugged, three-phase SCR power controller rated from 16 to 40 A, 100 to 500 VAC with an 0-5 V, 0-10 V or 4-20 mA control input. It offers zero cross firing for fixed resistance loads or phase angle firing for inductive and variable resistance loads. It is available with optional load diagnostics, which monitor SCR failure, total load and partial load failure. It may be used in environmental chambers, industrial kilns/ovens/ furnaces, infrared heating and glass melting applications.
