Introduction

1.1 Overview

The PowerPac Basic provides constant voltage or constant current to instruments used in
electrophoresis. The power supply operates at the values specified for the constant
parameter. However, to prevent damage to the electrophoresis cell, the PowerPac Basic
provides automatic crossover to constant current or constant voltage, depending on
which set value is first reached. When the set limit of the non-constant parameter is
reached, and the power capability of the unit is not exceeded, the power supply will
switch, making the non-constant parameter the new constant parameter.
