BNOS 13.8V 25A LINEAR PSU
Not much to say about this one. Fixed output, with a shut down circuit, presumably against overload.
FP301 13.8V 30A LINEAR PSU
This was the companion PSU to the FT301 that I owned many moons ago. It's a very fine 30A PSU and has a loudspeaker in the front grill.It's a bit tatty after all these years but nothing wrong with its electrics.
PALSTAR PS-30M 13.8V 30A LINEAR PSU
These well known and still manufactured PSUs are very reliable and feature variable output voltage with both voltage and current meters. They feature two independent low power 3A outputs in addition to the main 30A output.
