Electricity/Power Supplies
Low Voltage DC
Power Supply, Model
201L
This easy to use power supply
has the same “student
proof” short circuit and
surge protection as model
202L. This unit has the added
features of a digital voltmeter
and variable output
between 0 and 10 volts DC
with an output current of
2 amps. The variable voltage
selector allows fine tuning with a high level of precision when low values are
required. CSA approved.
1094M — $271.00
Low Voltage DC
Power Supply,
Model 202L
A voltage selector allows
easy output selection of
1.5V, 3.0V, 5.0V, 6.0V, 9.0V,
10.0V, DC. This unit is short
circuit protected and limits
output current to 2 amps.
In the event of a short circuit
the voltage is cut and
a warning LED lights up. An
electronic protection circuit
also protects from transient voltage surges. CSA approved.
1096M — $217.00
Low Voltage DC Power
Supply, Model 205L
A voltage selector allows easy
output selection of 1.5V or 3.0V
DC. This unit is short circuit
protected and limits output
current to 4 amps. In the event
of a short circuit, the voltage is
cut and a warning LED lights up.
Excellent “battery climinator” that
maintains an unvarying output
voltage. CSA approved.
1097M — $139.00
High Voltage Power
Supply, Model 122M
Equipped with a digital voltmeter
and a linear voltage
selector, this power supply
provides an output voltage
at any value from 40-300 DC.
Circuit protection limits the
output current to 50mA. Also
provided with this power
supply is a fixed secondary
output of 6.3volts, AC, ideal
for supplying vacuum tube
filaments or various 6V lamps.
In the event of a short circuit, the output voltage is cut and a warning LED will light
up. Only when the short circuit is eliminated will the protection circuit re-establish the
output voltage. CSA approved.
1104M — $347.00
Yacker
Tracker ®
A self-monitoring traffic light
sound meter. Green light
turns to yellow as a warning,
and then turns to red as
noise in the room goes above
the level set by the teacher.
Decibel sensitivity control
ranges from 50dB to 110dB.
Optional audible “quiet
please” (in four languages)
or siren can also be used, or
record your own message.
Delayed alarm function has
the siren sound when noise
continues for more than two
PE05551M
seconds. Lights can be automatically
or manually adjustable.
Includes meter to track
SN00172M
the number of times sound exceeds set level, long-lasting LED lights, reset button,
AC adapter, and optional face clings for lights. The 19-3⁄4" H x 5" W x 5-3⁄4" D unit can
stand alone or be wall mounted. Unit can also be run on six “AA” batteries (not included)
for mobile usage.120V AC. Sh. wt. 3.50 lbs.
SN00172M— $113.65
Deluxe Yacker Tracker ® . Same great features as the original Yacker Tracker ® , but this
model includes a remote. Put an end to climbing up and down to adjust the volume:
now you can hang your Deluxe Yacker Tracker ® anywhere and be in complete control!
Range for remote is up to 20 ft. Remote requires two “AAA” batteries (included).
Sh. wt. 3.50 lbs.
PE05551M— $149.35
Low Voltage Regulated Power Supply, Model 255L
This easy to use and multi-purpose power supply produces a regulated output
voltage from 0-15 VDC at a maximum of 5amps. It features a built-in digital ammeter
and voltmeter, dual potentiometer voltage adjustments (coarse: 0-15, fine: + 0.5)
and output current limitation adjustable from 0-5A. Voltage or current regulation
modes. CSA approved.
1100M — $391.00

The Remagnetizer
A revolutionary product that will save your science department money and time every
school year. Instead of throwing away expensive Alnico horseshoe and bar magnets
that have lost their magnetism, remagnetize them as often as you need to with the
Remagnetizer. Durable construction with aluminum frame, steel base with mounting
holes, and two permanent neodymium magnets. Requires no electricity. Magnetic poles
are marked N and S.
Sh. wt. 1.50 kgs.
SB22516M — $56.25
