BATTERY CONTROL VAN POWER PANEL

This is the Main Power Panel for the Battery Control Van and the M33 Acquisition Surveillance Radar. Three-phase line voltage is displayed on the meter being read by SP2 Hugh Mac Donald who is adjusting phase "C" for 120 volts. The three segmented meter on the left of the panel displays the regulated DC power supply voltages and is read by using the selector switch just below the meter.
