Power Supply for Electrophoresis

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. he PowerPac Basic has the following features: • Programmable constant voltage or constant current with automatic crossover • Timer control from 0 to 999 minutes • 3-digit LED display • Pause mode for editing running parameters • Automatic detection of no load conditions and rapid changes in resistance • Power Failure Detection in timed modes allowing completion of run • Stackable case with adjustable viewing angle via flip down legs
