Power Supplier. This power supplier, used in conjunction
with external power transistors takes in 34V to 40V and
gives a regulated 28V output. The output is current
limited at a value chosen to suit the external transistors
used and can be up to 6A. It is designed to power a range
of VHF power amplifiers. Power requirements 34-40V,
current required depends on parent equipment. 99mm x 27mm.
