SafetyCaution/Warning!!PowerPac power supplies use high output voltages that are electrically isolated from earthground to minimize the risk of electrical shock to the user. The following guidelines shouldbe observed and followed when using a PowerPac power supply.PowerPac power supplies have passed test for operation at temperatures between 0º and40º C, with relative humidity between 10 and 95% non-condensing. Operating the powersupply outside these conditions is not recommended by Bio-Rad and will void thewarranty.1. To ensure adequate cooling of the power supply, be sure that there is at least 6 cmclearance around the power supply. Do not block the fan vents at the rear of the unit.2. Always connect the power supply to a 3-prong, grounded AC outlet, using the3-prong AC power cord provided with the power supply.3. Bio-Rad electrophoresis cells have molded two-prong plugs that are inserted into thepower supply's high voltage output jacks. These plugs have been IEC 61010-1* certifiedfor safety compliance for use with PowerPac power supplies. Use of other plugs orbanana jacks is done at the user's own risk and is not recommended by Bio-Rad.When inserting and removing the molded two-prong plug, always grasp the plug by themolded support at the rear of the plug. Do not grasp the individual prong ends.4. Do not operate the power supply in extreme humidity ( 95%) or where condensationcan short the internal electrical circuits of the power supply.5. When taking the power supply into a cold room, the unit can be operatedimmediately. However, when removing the power supply from the cold room, let theunit equilibrate to room temperature for a minimum of 2 hours before using it.6. Never connect a high voltage output lead to earth ground. This defeats the floatingelectrical isolation of the power supply and exposes the user to potentially lethal highvoltages.ImportantThis instrument is intended for laboratory use only.This product conforms to the class A standards for Electromagnetic Emissions, intendedfor laboratory equipment applications.

Section 1Introduction1.1 OverviewThe PowerPac Basic provides constant voltage or constant current to instruments used inelectrophoresis. The power supply operates at the values specified for the constantparameter. However, to prevent damage to the electrophoresis cell, the PowerPac Basicprovides automatic crossover to constant current or constant voltage, depending onwhich set value is first reached. When the set limit of the non-constant parameter isreached, and the power capability of the unit is not exceeded, the power supply willswitch, making the non-constant parameter the new constant parameter.Output specifications:Voltage:Adjustable from 10 to 300 Volts, in 1 volt increments.Current:Adjustable from 4 to 400 milliamperes (mA) in 1 mA increments.Power:75 watts (maximum).Four output jacks:Up to four identical electrophoresis cells can be connected in parallelto the power supply.{FRONT PANELOUTPUT JACKSFig. 1.
