- Page 2 DESCRIPTION GENERAL The 9T92PVC2 series of Variable Transformer Controllers can be configured for one to three control channels. Each channel measures the output voltage from a variable transformer and controls the motor drive on the variable transformer to control the output voltage to a desired set point within a specified dead band. The unit can be programmed from an integral keypad or read and programmed remotely via a serial RS-232 port.
