Basler MVC 232 Manual Voltage Control Module
The Basler MVC 232 (part number 90 37000 103) is a manual voltage control module designed for generator excitation systems. This compact unit provides manual adjustment of the generator field current, allowing operators to manually control the output voltage when automatic voltage regulation (AVR) is not available or during commissioning. The MVC 232 is typically used as a backup or auxiliary control module in diesel gensets, marine power systems, and industrial generators.
The module features a simple, rugged design with a potentiometer for manual voltage adjustment and LED indicators for power and status. It operates on 60 V AC input and provides a regulated 55 V DC output for the exciter field. The MVC 232 is designed for panel mounting and includes screw terminals for easy connection.
