ABSOPULSE Electronics Ltd. 120W, Corona-free, 20kV Isolation Voltage DC-DC Converter DIO 120

20kVac isolation input/output, output/chassis Corona free at 10kVac Rugged, industrial quality Convection cooled - no fan Single output Fully electronic protection This series of DC-DC converters was developed for very high operating isolation voltage. The unit has a feedback system on the primary side which does not use any optical components to ensure high reliability. The transformer, which is engineered with ABSOPULSE’s field-proven proprietary technology, is tested for corona (partial discharge) extinction at a minimum of 10kVac and Hi-Pot tested for 20kVac isolation. The typical operating voltage potential between primary and secondary is 2-5kVac. This value depends on the specific application, contamination class and is limited by the creepage distance of 76mm (3.0”) on the PCB. Full electronic protection, low component count, large design headroom, and the use of components with established reliability result in a high MTBF. It is a lower cost version of the DIO 122 Series with single output - the encapsulated output chamber is not included in this design. The unit is manufactured at our plant under strict quality control. Customized versions are available.
