Control Relay
Crydom’s MCBC Series combines solid state technology with an advanced microprocessor control circuitry in a burst-fire controller to provide proportional power control to a wide range of resistive loads with ratings from 25 to 90 Amps at 48-530 VAC.
A proportional controller varies the power delivered to the output load by conducting a number of AC full cycles during a fixed time period, which is ideal for precise proportional control of resistive heaters.
Our MCBC Series analog input controller is available with several control input options: low DC voltage, 4-20 mA, or with internal potentiometer control. Two time-base periods are available depending on the resolution required: 10 AC cycles or 20 AC cycles.
