  Product introduction SUMMARYWisman＇s PRA modular high voltage power supply is ideal for OEM usage. It is specifically designed to meet the needs of applications requiring a hot switched reversible output voltage. The output polarity of the unit can be quickly and safely reversed via the Polarity Control Signal provided on the interface connecter. Both the output voltage and current are fully adjustable via ground referenced remote programming signals such that 0 to 10Vdc corresponds to 0 to 100% rated output voltage and current. Remote motioning functionality is provided by voltage and current test points such that 0 to 10Vdc corresponds to 0 to 100% rated voltage and current. Additionally remote polarity and mode indicators provide a compre-hensive overview of power supply operation. An optionalUSB 2.0、RS-232 or RS-485 is available .TYPICAL APPLICATIONS： Electrospinning Mass Spectrometry Capillary Electrophoresis Electrostatic Research DNA Analysis Microchip Electrophoresis Electrostatic Chuck (E-Chuck)OPTIONS： USB USB Interface RS232 RS-232 Interface RS485 RS-485 Interface 5VPM 0 to 5 Volt Programming and Monitor ScalingSPECIFICATIONS： Input: +24Vdc±10% .
