[Milsurplus] R&S SK310 PSU

[robert pearce]

Does anyone have information (a circuit diagram would be nice) for the power supply for an R&S SK310 1KW HF transceiver (BUD).

The power supply provides 24VDC start-up and 120VDS at 3KVA for the HV inverters. The PSU module is identified as IN 005 part number 410-1390,02

The design is rather special using transformers a chokes and 3 large stud mount SCR's of which one has gone S/C a/k. The unit weighs 40Kg+

I have original circuit information for the SK210 and 310 but it is incomplete i.e. no power supply (all in German) and fragile (1960's) folded paper.
