Bio-Rad PowerPac Basic Power Supply

The Bio Rad PowerPac Basic Power Supply, P/N 164-5050, 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.
