Basler MVC 108 Manual Voltage Control Module

The Basler MVC 108 is a manual voltage control module designed for local operation of generator voltage regulators. Identified by part number 9 0370 00 102, this module provides manual raise/lower control of generator voltage, allowing operators to adjust the voltage setpoint during commissioning, testing, and manual override situations. It is a simple and reliable interface for generator control applications.

Key Features

The MVC 108 features dedicated raise and lower pushbuttons for voltage adjustment. It includes status indication for power and operation. The unit is designed with fail‑safe logic and is housed in a compact, rugged enclosure suitable for panel mounting. Connections are via screw terminals for secure wiring.

Technical Specifications

Control voltage: 120 VAC or 24 VDC depending on configuration. Outputs: relay contacts for voltage raise/lower signals. Operating temperature: -10°C to +60°C. The unit includes surge suppression and transient protection for reliable operation. It is designed for continuous duty in industrial environments.

Operating Principles

The MVC 108 interfaces with the generator's AVR. When the raise or lower button is pressed, the unit generates a pulsed or maintained signal to the AVR, adjusting the voltage setpoint. Status LEDs provide visual feedback of the current state.

Applications

This control module is used in generator control panels, power plants, and industrial facilities. It is ideal for applications requiring local manual control of generator voltage.

Installation and Configuration

Mount the MVC 108 on a panel using the provided hardware. Connect the control power and AVR interface signals per the interconnection diagram. No extensive configuration is required; the unit operates according to the connected system.

Maintenance and Reliability

Routine maintenance includes visual inspection of connections and pushbuttons. The unit is built with high‑quality components for long service life.

Conclusion

The Basler MVC 108 manual voltage control module provides a simple and reliable interface for local generator voltage adjustment, ensuring operational flexibility.
