Heath Test Bench Power Supply

Other than some barely visible
top enclosure nicks and minor
scratches,I'm offering a near
mint,fully functional Heathkit
HP1175 voltage regulated bench
type DC power supply. Handy
device when bench testing 12VDC
amateur radio, household,
automotive,or marine battery
operated components. Can also be
used to power transceivers and
handhelds. Operates on either
115/220VAC input. Currently wired
for 115VAC. Has a convenient
front panel on/off toggle switch
and a pilot light. Output is
internally thumb wheel adjustable
from 13.0-15.0 vdc at a regulated
15 amps.Retrofitted with a dual
scale digital readout as depicted
in the photograph for the
simultaneous reading of both
voltage and current. A commercial
shunt has been installed to
facilitate the reading of current
up to 30 amperes.The unit has
been bench tested with a 12VDC
marine bilge pump (depicted in
the photograph) and functions
perfectly. The DC supply
regulated the voltage at the
preset 13.9 VDC and the operating
current is clearly evident at 2.8
amps. OEM Heath paint. $45+
shipping
