120W, Corona-free, 20kV Isolation Voltage, Dual Output DC-DC Converter DIO 122 Series • • • • • • 20kVac isolation input/output, output/chassis Corona free at 12kVac Rugged, industrial quality Convection cooled - no fan Dual output – 60W each Full electronic protection This series of dual-output DC-DC converters was developed for very high operating isolation voltage. Typical applications are high power gate drives, medical equipment, transportation and similar areas. The unit is designed and tested for corona (partial discharge) extinction at a minimum of 12kVac and Hi-POT tested for 20kVrms isolation. The typical operating voltage potential between primary and secondary is 6.5 – 10kVac, with the same isolation provided between the two outputs. Both outputs are highly regulated and have individual current limiting and short circuit protection. Isolation design features include encapsulating the output regulators in two separate insulation chambers, and the use of transformers engineered with ABSOPULSE’s field-proven proprietary technology. Output Voltages Two independent outputs: Any voltage in the range of 12V to 24V and up to 3A on each output. Consult factory for other voltages Input Protection Inrush current limiting Varistor Reverse polarity protection by crowbar diode Internal safety fuse Lower voltage than the specified minimum will not damage the unit Redundancy diode None Available as option Isolation 1.5kVdc input to chassis, 20kVac input to output, 20kVac output to chassis 20kVac output 1 to output 2 Corona extinction 12kVac minimum for the transformer Dynamic Response Max 5% voltage deviation for 10% to 50% load step, with better than 1msec recovery time Standards Designed to meet EN60950-1 and related UL & CSA standards EMI EN 55032 Class A with margins Switching Frequency: 100kHz ±5kHz 50kHz ±5kHz (for 24V input) Line/Load Regulation ±1% combined from zero load to full load including output separation diode Output Ripple/Noise Better than 200mV peak to peak or 40mVrms (20MHZ BW) Overload Protection Rectangular current limiting with short circuit protection. Current Limit set to: 3.5A ±0.4A Output Over-voltage Protection 30V transzorb on output Efficiency Min 80% at full load Operating Temperature 0ºC to 50ºC for full specification without derating Temperature Drift 0.03% per oC over operating temperature range Cooling By convection Environmental Protection Basic ruggedizing and partial encapsulation in the chambers with thermally conductive silicon potting compound with UL94V-0 flammability rating.
