The POWER-TRONICS PCMPC-B Master Phase Controller Control Module is an integrated phase control module designed for Power-Tronics B-model phase control systems. It combines phase control functions, AC input filtering, and an integrated 0-10VDC / 4-20mA interface module into a single compact control unit, simplifying installation and replacement in industrial power control applications.
The PCMPC-B is commonly used with Power-Tronics PC500B phase control systems for generator excitation, synchronous motor field control, and adjustable DC power supply applications. It provides precise voltage regulation through phase-angle control and supports external analog control signals from PLCs, VAR controllers, power factor controllers, or other automation devices.
This module features quick-connect terminals, manual voltage adjustment, remote adjustment input, and control signal interfaces, making it suitable for industrial generator systems, electrical power control cabinets, and retrofit replacement projects.
