Dual-output DC-DC Converter with 20kV Isolation Delivers 120W
Meets RIA 12 protection requirements. Oil and gas, railway, industrial, mining and medical environments. Absopulse Electronics has recently released a 24Vdc input version of the DIO 122 Series, a 120W high voltage isolated dc-dc converter. The unit now accepts inputs of 24Vdc (22 – 29V range), 48Vdc (44 – 56V) or 125Vdc (110 – 140). It provides two independent outputs, each capable of delivering any voltage in the range of 12V to 24V, with up to 3A on each output. Other inputs and outputs are available on request.The DIO 122 was developed for high power gate drivers and similar applications in oil and gas, mining, medical, railway and industrial environments. It is corona (partial discharge) free at 12kVrms (minimum) and each unit is Hi-POT tested for 20kVrms isolation. The typical operating voltage potential between primary and secondary is 6.5 to 10kVrms, with the same isolation provided between the 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. Creepage distances are more than 75mm. The DIO 122 is filtered to meet EN55022 Class A EMI as a minimum. It is convection cooled and rated for operation over 0°C to 50°C without de-rating. The open-frame package measures 102 x 70 x 305 mm (4” x 2.75” x 12”) and weighs 1.08kg (2.4 lbs). For detailed specifications, please see datasheet above (right). May 23rd, 2008 |
