Power Supplies
Power Supply, AC/DC
A solid state power supply with a built-in ammeter
and voltmeter. Separate DC and AC terminals provide
steady delivery of adjustable from 0–30 volts DC
and 0–40 volts AC (maximum load of 5 amperes). A
rear-mounted, grounded convenience outlet supplies
0–110 volts AC. Panel meters display DC volts and DC
amperes. Fuse protected with an LED pilot light and three-wire grounded plug.
Catalog No. Description Price/Each
AP4418 Power Supply, AC/DC $244.00
Power Supply, DC
Rugged, versatile power supply at an economical
price. Snap and banana plug terminals for
safe and easy connections. Large, easy-to-read
displays are available in either analog or digital
formats. Features a fail-safe current cutoff circuit
to automatically protect against overloads and
short circuits.

Analog 0–30 V 0–5 A $239.00
AP5903 Digital 0–50 V 0–3 A 258.00
Power Supply, High Voltage, AC/DC
Ideal for physics experiments requiring high
voltages. Three separately regulated, independent
supplies provide 0–1000 V DC at 10 mA,
0–50 V DC at 10 mA, and filament voltage taps
supplying 1–6 V AC in integer steps. Supplies
can be safely connected in any voltage pattern
due to the internal floating grounds. Large analog meter is easy to read and voltage
changes are as easy as turning the adjustment knobs. Eight 4-mm banana plug jacks.
33/4" x 10" x 81/2". Weighs 2.6 kg.

AP5792 Power Supply, High Voltage, AC/DC $850.00
Power Supply, Low Voltage, DC
Versatile DC power supply offers four-way variable
regulated power with overload protection. Each of
the four outputs from this power supply are precisely
held at specific voltage levels and are protected from
overload, shorts and excessive current demand.
Qualitative analysis of V=IR can be obtained using
simple calibration methods for analog meters.
Outputs: 12 volts DC at 1 amp, 0–20 volts DC at 2 amps, 5 volts DC at 3 amps.

AP9279 Power Supply, Low Voltage, DC $182.50
Power Supply, Dual Output, Low Voltage, DC
Two independent, fully regulated outputs. Each output’s
voltage can be continuously varied between 0 and 20 volts
with a current of up to 2 amps. Easy-to-read digital meter
that displays the current and voltage readings. Once set,
the voltage and current will be precisely held. A single 5-volt
at 2-amp regulated output is also built-in. For high-voltage
needs, the independent outputs can be used together. Externally controlled cutoff
circuit automatically protects against overloads, short circuits and personal injuries.

AP6530 Power Supply, Dual Output, Low Voltage, DC $329.00
Power Supply, Multiple Voltage Battery Eliminator
Convenient, fixed-voltage power supply substitutes
for a wide variety of batteries including AA, AAA, C,
D, and 9-volt types. Voltage is easily selected with
the turn of a dial. Designed so the output voltage
does not increase during adjustment between voltage
ranges. Connections are provided by two 4-mm
banana jacks. A fuse in series with supply output
provides short circuit protection. Plugs into a standard
electrical outlet, 120 V AC, 60 Hz, 1 amp max.

Vacuum Pump, Hand-Operated, Nalgene®
Easy-to-use pump made of high-quality, corrosive-resistant
polyvinyl chloride. Will maintain a vacuum of 25 inches of
mercury and hold this level constant for 24 hours. Aspringloaded
valve is provided so vacuum can be released without
disconnecting the pump from the line. The vacuum pump nozzle
fits 1/4" i.d. tubing with 2 feet of tubing provided with the pump.
Gauge monitors vacuum in both centimeters and inches of
mercury. Pump is sealed and self-lubricating. Intended for
siphoning, filtration, and indirect fluid transfer.
Note: For bell jars and vacuum chambers, use AP1597 vacuum pump.

AP2289 Vacuum Pump, Hand-Operated, Nalgene® $135.00
Vacuum Pump, Single-Stage
Low-maintenance, economical, single-stage vacuum pump
is fast and easy to operate. Oil-less operation produces a
moderate vacuum of 150 mm Hg (1/5 normal pressure). It
can also push a pressure of 3,192 mm Hg, which is 4.2 times
normal room pressure. Other specifications include 31 liters/
min. open flow, motor speed of 1725 rpm, 1⁄8 hp, gauges, on/
off switch on cord, carrying handle, rubber feet, 115 V, 60 Hz,
15 lbs. net weight. Accepts 1/4" i.d. tubing.
Note: For the classic Boil Water in a Bell Jar experiment, we recommend using the Two-Stage Vacuum Pump,
Catalog No. AP1597.
