SES-VC Series - SMART Motor Controller

The SES VC Series SMART Controller is a Silicon Control Rectifier (SCR) system designed to provide power management for 3 phase induction motors. Energy savings of 10% to 20% from most applications. Available for motors rated at 220VAC to 480VAC, 20A to 1000A.


By continually detecting the load change (delta Voltage/ delta Current) on a motor, a built-in microprocessor sends a firing angle signal to adjust the phase angle of AC voltage output accordingly. The size of the AC voltage phase angle depends on the actual loading. The phase angle control method provides a limited portion of each AC voltage cycle to the load, based on the percentage of power requested. The output is switched “ON” for a portion of every AC half cycle.


The result of this is reduced energy consumption, while maintain full operability of the target equipment.
