The Electronic Manual Voltage Control (MVC-301) is used as a back-up control device to provide
manual voltage control in case of voltage regulator failure. The unit can be mounted on a control
panel in ground vehicles, stationary equipment or shipboard locations.
The MVC-301 is a solid-state device enclosed in a metallic dark grey chassis and designed to be
'through-the-panel' mounted with the control accessible to an operator from the front of the panel.
A terminal strip located on the rear of the device facilitates installation and operation. An
AUTO-OFF-MANUAL voltage control mode switch is provided on the front panel.
Table 1-1 provides the electrical and physical specifications of the MVC 301.
