7.3.5 Power board

1. Power supply specifications
The power board differs according to the types of input power supply and antenna
revolving speed. See page.4-64 to 68.
Jumper setting inside the board performs switching between 100 to 115 VAC and 220 to
230 VAC power supply in a ship. Adjustments of input over voltage are required to do
this. Power supply outputs include + 24 VDC for the RF section, +24 VDC for the
TX-HV, +24 VDC for the antenna motor, +5 V, +12 V and –12 V power supply.
