Modular High Voltage Supply for Image Intensifiers
Spellman’s new DGM945 high voltage power supply for Image Intensifier applications continues to set the standards for high voltage power conversion technology. The DGM945 also has inputs to allow measurement ofthe photocathode current and getter current. The photo-cathode measurement has two ranges : sensitive range: 0 to 50nA and a standard range: 0 to 15µA. The sensitiveinput is used to provide a monitor output with a sensitivityof 0.1V/nA. The getter input allows measurement of the getter current, indicating if the Image Intensifier tube is still holding a good vacuum and is without gases causing ions.
Monitoring of all output voltages is possible via local test points or over the serial interface. The unit can also storeup to eight modes of operation. The output voltages are independently adjustable in each mode either by the rotary encoders built into the unit or via the serial interface.
The DGM series can be adapted to suit specific requirements with a wide selection of multiple output voltages and power capabilities in a compact package, making it perfect for the OEM user.
