Heath SP-27 low Voltage Power Supply For Sale:
The Heath SP-27 is the factory wired version of
the IP-27 kit version. It is a lab type power supply,
with adjustable voltage and current limiting.
It has a large 3.5 inch meter that can be
switched to read current or voltage.
The current limiting is set in 50 ma, 150 ma, 500
ma, and 1.5 amp ranges, with a pot for fine
adjust. One can set to the current expected,
and not let the smoke out as easily.
Specs say the voltage is adjustable from 0.5 V
to 50 V in 5 V steps. A pot permits fine adjustment.
On this unit, the ranges above 20 V are somewhat
compressed, and maximum output is 36 V DC. We
used supplies like this for over 25 years at the
college where I taught. Most of them do this
compression as they age. It is of no consequence,
as very seldom would one use over 15 V, and it
is perfect in the lower ranges.
Buy this power supply, with manual, for only
$60, plus shipping from Florida.
