Wireless Set No. 52 Cdn - Input Power

[Bob Carriere]

If a 52 set draws 22 amps on RX and TX at 40 amps,,,

How much does the 42 set draw in RX and Tx ....?

and how much does the 19 set draw....?
....any diffrence in A or B mode??

Figures I have for the 19 are A+B plus IC on 10A receive and 11.6A transmit.

HP Set transmit 18A.

The figures I have for the 52 are MCW on HP 45A, CW on HP 57A.
Receive is 3.3A, Standby 6.5A.

Prior to getting the AC supply for the 19 set I ran it from a pair of 12 batteries using a switch panel much like a C5 charging board. When one battery got down I could switch to a fresh one and the other one was connected to a charger.

I'm not aware of a "base" AC supply for the 52 set. There were other options for base sets like the C43 set.

There are switching supplies available now in fairly high current ratings like:

The problem with using a regulated supply is the inrush current to bring the dynamotor up to speed. The CPP2 is a brute force power supply. It only has rectification and filtering.

Maybe parallel a battery across a 12 supply.

The C42 is a fairly tame beast current wise. Assuming you are running it on a 24V supply, it draws the following amps:

Rx 4.9amps
Tx LP 5.5 amps
TX HP 8.3 amps

Communication range was rated at 15 miles HP and 4 miles on LP. The CPP2 driving it provides 11 amps in 24V DC mode and 22 amps in 12V DC mode, so it is more than capable of running the C42, a standard 19-set or even a vehicular mounted PRC-77 rig with a nice reserve.

Thanks guys.

Now I know that I can run the 42 and 19 on the CPP 2 power supply with no worries. I like Bruce's idea of using a good 12 volt bat. in parallel to handle the surge in demand.

Biggest challenge is negotiating a room in the house from the wife for the set up.

The ZE12 PSU was developed for use with the Remote 52-Set Receiver. I took a quick look in my 52-Set Manual and could not find a reference to the output amps for the ZE12. I assume it would be low, based on the draw for the receiver when in use.

Am I correct in assuming the ZE12 can only be used with the remote receiver, with the appropriate adapter cable that incorporates the large Marconi plug at the receiver end?

The ZE12 can only supply the receiver. If you look at the WS52 manual the actual main power supply consists of 2 motor generators and a vibrator supply.

One MG supplies 300 volts to the transmitter for low voltage circuits and the other MG supplies the plate voltage. The built in vibrator supplies the receiver.
When using the receiver as a remote you only need the vibrator equivalent hence the ZE12.
