The Electronic Manual Voltage Control MVC-300 is a solid-state device en

closed by a wrap-around metal chassis. The MVC-300 is for mounting through

a panel with controls accessible from the front of the panel or can be mounted

behind the panel. A terminal strip located on the rear of the device facilitates

installation. A manual voltage adjust potentiometer and a manual-off-auto

switch are provided on the front face of the unit. For use of a user-supplied

external manual adjust potentiometer or for adjust by a motor operated control

(MOC), order MVC-301. The MVC-300 and MVC-301 are designed to operate

with Basler voltage regulators powered from 120 or 240 volt AC sources up to

320 Hz. The adjustable output of the MVC-300 supplies power to 32. 63 or 125

volt fields at 7 amps.
