PP-3518 POWER SUPPLY is the internal power supply for the PRC-47 transceiver. Power input is 115 v 400 HERTZ . The transformer is also used as part of the DC to DC inverter to power the PRC-47 from 28 VDC. The components of the inverter are on the radio chassis, NOT on the power supply chassis and are NOT part of the PP3518. The PP3518 produces -110 vdc PA bias, -32 vdc driver bias, 1500 vdc, 650 vdc, + 300 vdc, +20 vdc, and 6.3 vac for the various circuits of the PRC-47. 16 lbs sh., #PP-3518, $25.00
Schematic for PP-3518 $4.00
