Peltier Heat Pump
High tech comes to Am Sci & Surp!! It is here in the form of a Peltier junction, a thermo-electric device that
translates electric power into heat, and perversely, into cool. Apply current @ 3-12 VDC to the gizmo and it
extracts thermal energy from one face, thereby cooling it. The heat is dumped onto the other face, thereby
heating it. Please note: you must use a heat sink on the hot side or the junction will fry itself, since it can
quickly create a 65° C temperature differential in a no load situation. Stack two, or build a cascade to
increase the thermal differential created. Or run it backwards. Apply heat or cold to the relevant face and
produce a current. Amazing for science projects and experiments. Practical for coffee warmers, beer coolers
and mini-refrigerator or warming oven applications. Comes with instructions. Small is 1.56" sq. x .15" thick,
large is 1.17" sq. x .12" thick.

Pro Power Supplies
A pair of regulated and filtered power supplies operating off 110 VAC, 60 Hz input and providing 13.8 VDC
output. PS-8 provides 6 amps constant, 8 amps surge output, (140 watts); ps-12 provides 10 amps
constant, 12 amps surge output, (200 watts). Both are MG Electronics’ Pro Power™ products. They are
thermally protected (auto reset), have input fuse protection, short circuit protection (auto reset), Voltage
surge protected and have low ripple. Roughly 5–1/2” x 4” x 9”. Very nice, well built general duty supplies.
