Series GMA MINIATURE HIGH VOLTAGE DC-DC CONVERTERS FEATURES 1.5W continuous output power PCB Mounting Small size Outputs up to 3kV Positive or negative polarity Output proportional to input No minimum load requirements Input polarity protected Open and short circuit protected EU RoHS Compliant to 2002/95/EC Marked (LVD) Ripple: DESCRIPTION 1% peak to peak (0.1% for Screened Case version). The Series GMA is a unique range of low cost, general purpose Efficiency: high voltage DC to DC converters. All units are configured for Better than 50% at 1.5W load. direct PCB mounting and are intended to be designed in to the customers equipment as a component. The Series GMA is suitable Oscillator Frequency: for ink jet printing, electrostatic precipitation, Geiger-Muller tubes, 25kHz to 200kHz depending on model. photomultiplier tubes, electron beam deflection and focussing, as well as various general purpose applications. Protection: Protected against intermittent flashover. If none of the standard models in this datasheet suit your requirements, please contact our sales team about a custom version. Operating Temperature: 0 to +40oC. SPECIFICATION Options: Output Power: Screened Case: Screened case of tin plate construction with its 1.5W max continuous. own pin reduces radiated noise and output ripple. Output Voltage: Isolated unit: Isolated units give input to output isolation of up to Units available with maximum output voltages from 100V to 3kV. 100V. This can allow, for example, a sense resistor to be added for load current measurements. A Input Voltage: capacitor may be added between the input 0V and 12V or 24V DC. output 0V to reduce common mode ripple. Polarity: Operation: Positive or negative to order. The unregulated output is proportional to the input voltage. Alternatively external feedback control loops can be added to provide regulated Load Regulation: outputs. The converters are vacuum encapsulated in an ABS case Typically less than 10% (for a 0 to 1.5W load change), maximum 20%. to ensure maximum reliability and safety. Standard GMA models are three pin devices which provide a common 0V for input and output. All Line Regulation: models are available with a range of input and output voltages, with Output is proportional to input over a 10% to 100% input range, with a either positive or negative output. variation of 10% or rated output voltage. www.hitekpower.comSeries GMA MINIATURE HIGH VOLTAGE DC-DC CONVERTERS Safety: This DC-DC converter meets the requirements of the Low Voltage Directive (LVD) 73/23/EEC, by complying with BS EN60950 when it is installed as a component part of other equipment and is CE marked accordingly. RoHS: The Series GMA meets the requirements of EU Directive 2002/95/EC on the Restriction of use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS).
