IMPORTANT GUIDELINES
Introduction
The important guidelines for operating the peqPOWER 250 Volt Power Supply are provided in this sec-
tion. We recommend that you carefully review these guidelines before operating the instrument.
Important
For best results, do NOT use the peqPOWER 250 Volt Power Supply at its maximum electrical load lim-
its. Variations in buffer conditions can result in exceeding the power supply’s maximum voltage, current,
or power output capacity and produce undesirable variations in electrophoretic separations.
General Operating Instructions
Follow the instructions below to operate the peqPOWER 250 Volt Power Supply.
Turn on the peqPOWER 250 Volt Power Supply using the power switch on the rear of the in-
strument. Upon start-up, the current settings appear on the screen.
Use the START/PAUSE and STOP keys and output jacks for applications.
Use the CONSTANT key to set up operation mode.
Recommendation
The duration of electrophoresis can be defined in time (hours/minutes). When using this or any electro-
phoresis product, we recommend that you adhere to the protocols given in the electrophoresis product
manuals, and durations, specified in time.
Important
For best results, follow these important guidelines when running multiple gels and electrophoresis units
concurrently.
For example:
• Avoid running samples of widely differing salt concentrations or sample buffers at the same time or on
the same gel.
• Properly prepare and desalt your samples.
Note: Variations in conductivity due to differences in buffer salt concentrations can affect the run of all
the samples run at the same time.

CHOOSING LIMITING PARAMETER SETTINGS
Introduction
The peqPOWER 250 Volt Power Supply is capable of operating at limiting Voltage, or limiting Current
or limiting Power. We recommend operating the peqPOWER 250 Volt Power Supply at limiting voltage
for most applications. See below for more details.
Voltage Limiting
For most electrophoresis methods resistance increases throughout the run. Limiting the voltage provides
the following advantages:
Current and power decrease throughout the run, providing an improving margin of safety over
time.
The same voltage setting can be used regardless of the number or thickness of gels being elec-
trophoresed.
Current Limiting
Discontinuous buffer systems and, to a lesser extent, continuous systems increase resistance during the
run. If you use the current limiting setting on the peqPOWER 250 Volt Power Supply, the voltage will
increase as resistance increases to satisfy Ohm’s law (V=I*R). If no voltage limit is set and a local fault
condition occurs, such as a poor connection, very high local resistance may cause the voltage to in-
crease to the maximum capacity of the power supply. This may lead to local overheating and damage
to the electrophoresis cell or create unsafe conditions. When operating under constant current condi-
tions, set a voltage limit on the power supply at or slightly above the maximum expected voltage.
Power Limiting
Power P is a function of voltage V and current I P=I*V. If voltage is increased power will also be in-
creased depending on the gel system, resistance R should be a constant. Power will be reflected by the
heat generated during a gel run. The power limiting function may be used when running sequencing
gels to remove the APS from the wells and to heat the gel to an optimal temperature for DNA separa-
tions.

OPERATIONAL ELECTRICAL PARAMETERS
Power Considerations
Electrophoresis is the migration of a charged particle under the influence of an electrical field. The
power supply output parameters voltage, current and power are related by the following two equations:
Voltage (V) = Current (I) x Resistance (R); (V=I*R)
Power (P) = Current (I) x Voltage (V); (P=I*V)
Resistance
Resistance of the assembled electrophoresis cell is dependent on the conductivity of the gel buffer, the
thickness of the gel, and the number of gels being run. Although the resistance is determined by the gel
system, the resistance can vary over the course of an electrophoretic separation. For instance, in the
Tris-Glycine buffer system, the fast moving, highly conductive chloride ions in the gel are gradually re-
placed by the slower moving, less conductive glycine ions from the running buffer as the gel runs. As a
result, the resistance of the gel increases as the chloride/glycine front moves down the gel, and the cur-
rent decreases.
Voltage
The velocity with which an ion moves in an electric field will vary in proportion to the field strength (volts
per unit distance). The higher the voltage the faster an ion will move.
Current
Current is a function of the number of ions passing a given cross-section of the circuit at a given time.
For a given gel/buffer system, at a given temperature, current will vary in proportion to the field
strength (voltage) and/or cross-sectional area (number and/or thickness of the gels). Ions in solution
and at a given voltage will move faster as the temperature increases, increasing current.
Power
The power in Watts, or the rate of heat generated by the system, is directly proportional to voltage and
current (P=I*V).
COMMON ERRORS FOUND WITH ELECTROPHORESIS POWER SUPPLIES
No load
The electrophoresis system is not connected to the power leads, check the power leads
The electrophoresis system has a short, the Pt wire is broken or the banana connectors are dam-
aged
Buffer concentration too low
Buffer volume too low
Short in power cord
Current has dropped below acceptable rating (10 mA)
PEQLAB_v0412E 12

Instruction Manual peqPOWER 250 Volt Power Supply
Short circuit
Load exceeds 3000 mA
Blown fuse in the power supply
Incorrect input voltage (check input voltage switch near power inlet)
Change in load
Electrophoresis systems were added or removed during a run
Buffer leaking in a connected system
Excessive temperature increase
Excessive buffer evaporation
Loose connection in a connected system
Amperage set to low
Change in constant mode
Voltage changes to amperage
oAmperage set too low. Ceiling hit and constant mode changed from voltage to amper-
age. Increase amperage to 3000 mA.
Amperage changes too voltage
oVoltage set to low. Ceiling hit and constant mode changed from amperage to voltage.
Increase voltage to 250 volts
The 250 volt system has automatic cross over, set voltage or amperage, and preset wattage. During the
electrophoresis process only one parameter is limiting at a time. The limiting parameter, together with
the conductivity in the electrophoresis system, and the values for the other parameters determine the
maximum output.
