Tabletop power supply MSA series

AC/DCswitchingwith short-circuit protection

Variable Voltage Programming Voltage Monitor The MSA Series are compact printed circuit board mountable (PCB) high voltage power supply module available from 1kV to 3kV with either a positive or negative output polarity. The MSA Series feature 0-10Vdc variable voltage programming that equals 0-100% of rated output voltage. A voltage monitor is provided where 0-10Vdc equals 0-100% of rated output voltage. Additionally a status signal and enable signal provides simple control of the power supply. All units have in-built protection against fault conditions. The MSA Series are intended for general use where a compact high performance PCB mountable power supply is required, like driving an electron multiplier in a mass spectrometer. The aluminium enclosure helps shield the unit reducing radiated noise. Typical applications: Photomultiplier Tubes Electron Multiplier Mass Spectrometry Electrostatic Lenses Nuclear Instruments SPECIFICATIONS Input Current: 150mA maximum input current 30mA pk-pk maximum input current ripple Output Polarity: Positive or negative, specify at time of order Output Voltage Accuracy: ±1% Voltage Regulation: Load: 0-100% rated load, ±0.02% Stability: 50ppm/8hrs after one hour warm up period Temperature Coefficient: 25ppm per degree C Settling Time: After Power On or Enable 100 milliseconds, typical When power is removed the unit will decay to <±60 volts within 2 seconds Protection: Not designed to withstand continuous arcing Environmental: Temperature Range: Operating: 0˚C to 60˚C Storage: -20˚C to 70˚C Humidity: 95% RH, non-condensing Cooling: Convection cooled
