Cosel co, japan, has introduced a wide range of converters. They include inputs ranging from 4.5 v dc to 75 v dc in addition to wide range of versions from 36-72 v dc and 88-370 v dc for static and dynamic robotics and remote control operation. All units are assembled with smd components and have maximum profile heights from 7 mm to 8.5 mm. Additional built-in heat sink of 3 mm width renders 50 w/100 w units to 12 mm profile height. Pin board mountable converters with single and dual outputs come from 5 v to 30 v dc output. It incorporates externally adjustable trim control pin and remote control pin. With current balance/voltage balance mode of operation for paralleling function, current sharing improves delivery of converters to 500 w and above. All converters operate from -20°c to 70°c with storage temperatures extending from -40°c to 85°c. Ac/dc rectifier front ends come in smd modules with 750 w handling capability. These incorporate unity power factor at input, zero crossing detector inrush limiting and rfi/emc control with iec 1000-3-2 and radiation approvals of cispr 22.2. All modules conform international safety approvals of ul/csa/tuv/en and iec apart from dentori.
