Harris RF-5051-PS001


These are line powered power supplies that output "24 VDC" so allow using equipment designed for military vehicle use in fixed installations.

The Harris RF-5051-PS001 is much smaller and lighter than the PP-6224.

The PP-6224 allows using vehicular equipment at fixed or airborne  locations where AC power is available
This is a portable power supply that has two outputs that can supply "24 Volt" power at up to 25 Amps total.  It's input can be either AC (115 or 230 VAC & 50, 60 or 400 Hz) or a "24 Volt" battery with automatic switchover to the battery if the AC fails.

My hope is that I can power any one of the radios in the GRC-206 system (GRC-206 on the PRC-104 web page, MT-6250 Mount and details).

The rear panel connectors J3 & J4 can be used to power equipment or to charge a "24 Volt lead acid battery".

Form, Fit & Function interchangeable with PP-2953.

May be similar to the M455-1/GRC-206 Power Source

For AC operation the CX-11979 (NSN: 5995-00-135-4555)  cable is needed and it attaches to the front panel.  Too bad, because this means that the front panel cover needs to be open.  Attaching to the rear panel would allow closing the front panel cover, but maybe there's a good reason for this, will see once it's running.
The connector on the power cable is the MS3116F-14-5S.  The front panel connector has 3 lugs and an O.D. of 7/8".  See Hints & Tips for AC Wall Outlet Wiring.

When shopping for the cord I looked at ready made 12/3 extension cords with the idea of cutting off the socket, but for less money I could get Oil resistant 12/3 cable (which is more flexible than the yellow or orange plastic cable used to make the ready made extension cords.  Also since you're buying the cable by the foot you can get whatever length makes sense for you.  In this case 20' seemed better than 25' for a ready made cord.

The fan comes on with the AC power and although noticable is not too objectionable in terms of how loud it is.
