OPERATING INSTRUCTIONS
SAFETY PRECAUTIONS
Use only a polarized 3- wire ac outlet. This assures that the power
supply chassis, case, and ground terminal are connected to a good
earth ground and reduces danger from electrical shock.
There is little danger of electrical shock from the power supply
output, which produces a maximum of 30 volts dc. However, there
may be great danger of electrical shock if the power supply
output is connected to an external high voltage. Some equipment
being powered may contain high voltage and present a shock
Do not exceed the voltage rating of the circuit being powered.
Many transistors and integrated circuits will not withstand
voltage of 30 volts.
There is no need to worry about voltage spikes or overshoot
damaging the equipment under test. The voltage between the
output terminals of the power supply never exceeds the preset
value as the POWER switch is turned on or off.
HOOK- UP
hazard. Observe caution. If the power supply output is floated
(referenced to a voltage rather than earth ground) turn off the power
supply and the equipment under test when making connections.
Never float the power supply to a potential greater than 100 volts
peak with respect to earth ground.
EQUIPMENT PRECAUTIONS
Avoid using the power supply in ambient temperatures above
+40° C. Always allow sufficient air space around the heat sink at

Turn off the power supply and the equipment to be powered
during hook- up.
Connect the positive polarity of the device being powered to
the red (+) terminal of the power supply.
Connect the negative polarity of the device being powered
to the black (-) terminal of the power supply.
Fig. 3 illustrates the grounding possibilities.
a. If the negative polarity of the equipment or circuit being
powered is also the chassis or common, it may be
grounded to earth by strapping the black (-) terminal to
the rear of the power supply for effective radiation to prevent

b. Similarly, the positive polarity can be grounded by
Although the power supply is protected against reverse polarity
damage, the circuit being powered may not include such protection.
Always carefully observe polarity; incorrect polarity may damage
the equipment under test.
