Instruction Manual peqPOWER 300 Volt Power Supply
OPERATIONAL MODES
Introduction
The peqPOWER 300 Volt Power Supply is designed to operate under two modes, Constant Voltage
mode or Constant Current mode, depending upon your electrophoresis application.
Use the Constant Voltage / Constant Current Mode for applications that require only one specific volt-
age limit or current limit during the entire duration of electrophoresis.
Display Screen
The Display Screen illuminates after turning on the power to your instrument and the factory default
settings (or last settings) will be displayed. You can choose the operational Mode (Constant Voltage or
Constant Current Mode) by pressing the “constant” button.
On the Display Screen:
- The chosen constant parameter (Voltage or Current) is displayed in bold on the left
side of the display.
- The Timer is the first line on the right-top, and the non-constant value is displayed in
the second line on the right side of the display screen.
Basic Constant Operation Protocol
The Constant Voltage and Constant Current Modes allow you to specify a voltage limit, and current limit
to be used continuously during the entire duration of electrophoresis. Review the guidelines provided in
this manual before starting electrophoresis using the peqPOWER 300 Volt Power Supply.
A basic Constant Voltage / Current Mode operating procedure of the peqPOWER 300 Volt Power Sup-
ply is provided below. We recommend reading the guidelines provided in this manual for best results
before starting an operation.
1. Use the power switch on the rear side of the instrument to turn on the peqPOWER 300 Volt
Power Supply. The Display Screen will illuminate.
2. Press the CONSTANT key to select either Constant Voltage Operation or Constant Current Op-
eration from the Display Screen.
3. Use the Up arrow / Down arrow keys to set either voltage (V) or current (mA) parameter to the
appropriate values.
4. Press the MODE key to choose the TIME parameter, and use the Up Arrow / Down Arrow keys
to set the duration (hours/minutes) of the electrophoresis run.
5. Press START/PAUSE key to start electrophoresis.
6. Press the START/PAUSE key again to temporarily interrupt power. The red “Run”LED will flash
to indicate that the electrophoresis run is paused. Pressing the START/PAUSE key again will re-
start the electrophoresis run.
7. Press the STOP key to permanently stop the electrophoresis run (the timer will reset).
8. To change the limits (Voltage or Amperage) of the electrophoresis run in progress: Press the
Mode key. Enter the changes using the Up Arrow / Down Arrow keys, and then press
START/PAUSE key once again to restart your operation.
