Manual Power Supplies
Very important
This electrophoresis power supply is a high technology instrument available in several versions. As it is
capable of giving dangerous voltage levels by which high power is involved, we suggest that you take a
few moments to read this manual thoroughly. Although this instrument is equipped with all necessary
safety features against abuse and other accidental failures, caution should be exercised when working
with high voltage equipment.
1. Avoid to tou h the outlets with any ondu ting obje t and make sure there is a second person
present for your safety in case of any severe electric shock.
2. Never touch any part of the assembly (power supply, leads or tank) before having switched off.
3. Never manipulate with wet hands.
4. Do not ground any of the outputs or the buffer in the tank.
5. onnect the outlets only to an insulated electrophoresis tank with safety cover.
6. Never make any other connections, such as e.g. putting several power supplies in series or in
parallel.
7. In order to prevent electric shock, never open the back plate nor remove the cover.
8. Do not expose the unit to rain or any other liquid.
9. Do not spill liquid or insert metal obje ts inside the unit. Take care so that the power supply is
not dropped to avoid damaging the cabinet which defeats safeguards or injuring yourself.
10. If the unit has been dropped or the cabinet has been damaged, unplug it and have it checked by
an authorised service technician to restore the safeguards.
11. The fact that the unit operates satisfactorily does not imply that the unit is properly earthed or
that it is completely safe. If in any doubt about the effective earthing of the unit, contact a
qualified electrician.
12. Never blo k the ventilation holes or place the unit in any enclosure unless proper ventilation is
provided.
13. Never place the unit near or over a radiator, heat register or stove.
14. Avoid locations where the instrument is exposed directly to the sun light.

Alarm messages
In case a problem or a hazardous situation is detected, the power supply will intterupt the experiment
with one of the following errors. A sound will also be produced that can be stopped by pressing any key.
The hazardous situations require that the power supply needs to be switched off before starting the
experiment again.
•GROUND LEAKAGE
A dangerous ground leakage is present (check thoroughly the complete assembly). Your power
supply is NOT defective! See Frequently As ed Questions at the end of this manual.
•SHORT-CIRCUIT
onnected tank is short-circuited or has a very low resistance (check thoroughly the complete
assembly). Your power supply is NOT defective! See Frequently As ed Questions at the end of
this manual.
•OVERLOAD
onnected tank has a too low resistance (check specifications). Your power supply is NOT
defective! See Frequently As ed Questions at the end of this manual.
•LOW CURRENT
The output current is very low (switch the alarm off in the SETUP menu). Your power supply is
NOT defective! See Frequently As ed Questions at the end of this manual.
•TECHNICAL PROBLEM
Failure in the electronics. See Support on www.consort.be. You could also try a general RESET:
switch the instrument on while holding  pressed. Attention! All stored programs and data will
be erased!
USB Digital Port
This power supply has a digital USB port allowing to interface with a computer. Programs can read and
control the power supply completely. More information can be found on our support website.

Manual Power Supplies
Frequently As ed Questions
What are the relations between Voltage, Current, Power and Resistan e?
Power (W) = Voltage (V) x urrent (A)
Resistance (W) = Voltage (V) / urrent (A)
How does a power supply rea t after pressing RUN?
The internal generator will start building up the high voltage at the output terminals while voltage and
current are constantly measured and power calculated. When one of the pre-set parameters is
exceeded, the generator stops and will keep that parameter constant.
How important is the resistan e of an ele trophoresis unit?
The resistance of an electrophoresis unit depends on its size, gel thickness, amount of buffer, buffer
conductivity and temperature. This resistance will normally decrease in time due to a slowly increasing
temperature. Electrophoresis units which have a resistance below the minimum load resistance of a
power supply will trigger an alarm! Read the output voltage and current during a run to measure the
resistance and use above formula to calculate the value.
How to keep a onstant voltage during a run?
Program the desired voltage and a higher current and power then the maximum expected values:
urrent > Voltage / Resistance
Power > Voltage x urrent
How to keep a onstant urrent during a run?
Program the desired current and a higher voltage and power then the maximum expected values:
Voltage > urrent x Resistance
Power > Voltage x urrent
How to keep a onstant power during a run?
Program the desired power and a higher voltage and current then the maximum expected values:
Voltage > urrent x Resistance
urrent > Voltage / Resistance
Why are my output values different from those of a similar experiment?
Either your programmed parameters are not equal to those described or the resistance of your
electrophoresis unit is different (see above). It cannot be due to e.g. an other model of power supply as
the relations between Voltage, urrent, Power and Resistance are monitored in the same way by any
instrument (the electrical laws cannot be disregarded!).
What about onne ting more than one unit to the same power supply?
The outlets being in parallel each electrophoresis unit will be supplied with exactly the same voltage.
However, current and power may differ due to differences between them even when exactly the same
model, gel, buffers, etc... are used. Therefore, it is recommended to run several electrophoresis units
only in the constant voltage mode on the same power supply.
Mind also that adding tanks will increase the current and the power. These parameters may be limited
by the power supply and cause it to switch over to constant current or constant power.
