[Milsurplus] 24 volt 40 amp switchers

[Ray Fantini]

I have a bunch of MGV PH1003-2440/RS 24 volt 40 Amp switching supplies from a analog television transmitter that I am junking. They are adjustable from 24 to 31 volts and were designed for continues operation in television service.
The bad news is that they were designed for three phase 340 to 460 Volts AC input. Have not tried it yet but wanted to see if they will work from signal phase 408 being modern switching supplies have no transformers or anything like that on the input side. They just take the incoming lines and run them to a huge bridge rectifier and feed that to the switching circuit. I did try one on 208 but it did not start up.
If anyone wants one to play with you can have one for $20 each plus shipping.
Expect to have a bunch of linear regulated 24 volt supplies from a from a Comark transmitter as soon as I get permission to star junking that, you may be unaware of it but the television industry is going thru changes unlike anything in the past where an entire fleet of analog and high channel digital transmitters are all being junked. At one site I work at we have the remains of the analog 60 kW transmitter all over the parking lot at another the solution was to disassemble it in place and get rid of it that way.
