Notes Power Junction Box for AN/ARC-3 VHF Radio.

The Junction Box serves as the junction point for all interconnecting cables between the receiver, transmitter, power source and control panel.
On top of the unit are 2 dynamotors mounted which supply the anode voltage for receiver and transmitter.

DY-22/ARC-3 is the smaller of the two dynamotors. it runs continuously to supply the receiver with 210 VDC. DY-21/ARC-3 is the larger of the two units to supply the transmitter with 410 VDC. It is energized only when the PTT key is pressed.

Variant J-68A/ARC-3 is identical to the basic unit except for different fuse holders.

Power consumption (28 VDC) : receiving 5.5 A / transmitting 12 A
The total weight of approx. 20 lb does include both dynamotors.
