Safety Features:
• Load connect detection - unit will display an error unless a
connection is made.
• Short circuit detection - unit will display an error if the
current is too high.
• Loose connection detection - unit will display an error if the
current keeps changing.
• Recessed terminals - terminals are recessed to safely
accommodate leads.
• Protective casing - minor liquid spills can be easily wiped up.
Current-Voltage Relationship
V=IR
V = Voltage, I = Current, R = Resistance
Ohm’s Law states that the voltage (V) through a conductor is directly
proportional to the current (I). The constant of proportionality is the
resistance (R).
Therefore, our power supplies can be set either to a constant voltage or a
constant current, however they cannot both be controlled at once. The
resistance is determined by a number of factors including the device that
the current is being applied to, and any buffer or gel in that device.

1. Turn unit on on using the switch on the rear of the unit next
to the plug.
2. Use the up or down arrows to the right of the screen to
select the desired voltage (default is set to 125 V).
3. Use the right arrow below the up & down arrows to
move to the “time” mode and use the up arrow to set the
run time (refer to kit or experiment instructions for appropri-
ate run time).
4. Once the parameters have been set, secure the leads to
both the device or chamber and the appropriate red and
black receptacles on the power supply.
5. Press run/pause button to begin. For electrophoresis,
continue to occasionally monitor the tracking dye in the
samples to ensure they do not run off the end of the gel.
6. To pause the electrophoresis run, press the run/pause
button. Make sure there is no current running before
removing the lid. You may resume the run where you left off
after securing the lid.
7. To stop the power, press the stop button .
TO USE AT A CONSTANT VOLTAGE:
1. Turn unit on on using the switch on the rear of the unit
next to the plug.
2. Press the right arrow below the up & down arrows
twice to move to the "set current" mode.
3. Use the up or down arrows to the right of the
screen to select the desired amperage (default setting is
500 mA).
4. Use the right arrow below the up & down arrow to
navigate to the "set time" mode, and use the up arrow to
set the time (refer to kit or experiment instructions for
appropriate run time).
5. Once the parameters have been set, secure the leads to
both the device or chamber and the appropriate red and
black receptacles on the power supply.
6. Press run/pause button to begin. For electrophore-
sis, continue to occasionally monitor the tracking dye in
the samples to ensure they do not run off the end of the
gel.
7. To pause the electrophoresis run, press the run/pause
button. Make sure there is no current running before
removing the lid. You may resume the run where you
left off after securing the lid.
8. To stop the power, press the stop button .
TO USE AT A CONSTANT VOLTAGE/AMPERAGE:
