The CTRCT-1 and CTRCT-2 regulator boards are current trip regulators with current transformer (CT) feedback. Both boards provide current regulation in ac controller configurations with a latching overcurrent trip that may be configured for automatic or manual reset. The CTRCT-2 provides enhanced functionality with optional voltage regulation, potentiometer adjustable ramp time, transistorized status signals indicating overcurrent , current limit, and trip reset.
The CTRCT-1 and CTRCT-2 boards utilize current feedback from CTs on the single-phase or three-phase mains. A diode rectifier and burden resistor generates the current feedback signal required for the regulator circuit.
