This high efficiency high voltage DC/DC converters family offers up to 12 kV Outputs designed to supply Detectors, Imagers, Spectrometers, Avalanche Photo Diodes, Photo Multiplier Tubes. These units include: No Input Single Point Failure, Latch-Up Protection Circuit, ON/OFF Control, as well as Selectable Soft Start and Latch Delay, SYNC Input and Thermal protection.
The largest HV system ever developed in a standalone solution. The HV-box, developed in the frame of JAXA CALET experiment, is able to supply a large number of different HV channels (102) for photo-detectors of PMTs and APDs. The experiment has been installed on Japanese Experiment Module of ISS.
Among the 80% electronics provided by SITAEL for all sub-detectors of AMS-02 Experiment, one of the main developents is the entire high voltage power supply system. The system is based on the HV Brick, a fully rendunded and modular set of interconnected modules including DC/DC converters to generate high voltage from the 28 V DC available from the space station, linear regulators to fine adjust the voltage of each photomultiplier and logic board with the digital link that sets and monitors the various voltages.
SITAEL designed and produced the Engineer Model, Qualification Model and Flight Models of the 6KV/30mA High Voltage power supply systems for the INTEGRAL/JEM-X Microstrip Gas Chamber. The JEM-X HV power supplies, launched in orbit with the INTEGRAL satellite on October 17th 2002, are successfully working. Their smooth operation showed so far proves the reliability of the SITAEL vacuum-borne products.
Invited by ESA/JAXA for a direct negotiation, SITAEL developed and produced, in the frame of a contract with OHB, the High Voltage Power Supplies (HVPS) to be used in the Soft Gamma ray Detector (SGD), the Hard X-ray Imager (HXI) and the Soft X-ray Spectrometer (SXS) of the ASTRO-H satellites.
In the frame of a contract with COMDEV Canada, SITAEL developed the High and Low Voltage Power Supplies for the Suprathermal Ion Imager of the Canadian Electric Field Instrument aboard the SWARM constellation of satellites.
