BIO-RAD PowerPac 300

Here is a BIO-RAD PowerPac 300 for sale. This instrument has been tested by our in-house service technician and is ready for use.

The PowerPacs are programmed with default limit values for voltage and current. These are the values which are available when the unit first is turned on. These values may be changed for each application.

The power supplies operate at the values specified for the constant parameter. However, to prevent damage to your electrophoresis cell, both PowerPacs provide 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.

The PowerPac 300 power supply offer a number of features, including the following:

• Constant voltage or constant current operation with automatic crossover.
• Timer control.
• Viewing angle adjustment.
• 3-digit LED display.
• Stackable case.
• Automatic detection of no-load conditions and rapid changes in resistance.
• Automatic completion of a run interrupted by a power failure, when user enabled.
