For Sale:
Heath IP-27 DC "lab type" power supply
This supply is capable of up to 50 V DC at up to 1 1/2
amps of current. It is set up in 5 volt ranges (0 to 5 V,
5 to 10 V, etc), with a bit of overlap on the ranges, and
then has a pot to set the fine voltage. Heath used a neat
design, where the power transformer has many taps,
and is switched as one changes ranges, keeping heat
and power dissipation to a minimum. The current
limit has 4 ranges (50 ma, 150 ma, 500 ma, and 1.5
amps), with a pot to set the fine adjustment. It also has
a very large (approx 5 inch) meter to read the voltage
and current.
This one works great, and looks fine also.
With paper work for $85.
Keithley 169 Lab Quality Digital Multi Meter
This is a bench type DMM, with good accuracy.
3 1/2 digit LCD display
Voltage ranges are protected to 1400 volts
Resistance ranges are protected to 300 V RMS
(This means you can accidentally apply up to 300 V
RMS when measuring resistance, and the meter
will survive.)
Voltage ranges from 200 mv to 1000 V
Current ranges from 100 microamps to 2 amps
Resistance ranges from 200 ohms to 20 Meg
It is in very nice condition, both electrically and cosmetically.
Manual included for $80.
Prices do not include shipping from Florida.
Thanks.
