The 90-250Vac universal input allows them to be used worldwide. Flexibility options include an isolated V4 output. Output voltage options are given in the table below. Models with EN55022-B conducted emissions and fully custom models are also available. Contact the factory for details. The US50 is one of the flexibility series. In addition to the models listed on this sheet, many potential models are available that include full safety agency approval and do not require any non-recurring engineering (NRE) charge. Prototype delivery is just a few weeks. US50 models are also available with 12Vdc, 24Vdc or 48Vdc inputs. Please see the DP50 Series data sheet for details. Specifications are subject to change without prior notice. Available Models Notes: 1 At least 20% of maximum output current (Im) is required to maintain stated regulation. Supply remains on at zero load, but regulation is not guaranteed. 2 Convection cooling, 40W maximum9 3 Forced air cooling, 50W maximum9 4 Peak output, 30 sec max 5 The US50 series allows very fast flexible modified standard designs within these parameters without non-recurring engineering charges and while retaining safety agency approvals. Please contact the factory for details. 6 Can be specified in 0.1V increments 7 Can be specified in 0.75V increments 8 Operational extremes per safety agency testing 9 Under certain input, output and/or cooling conditions, maximum continuous output power may be as high as 50W with convection cooling and 60W with forced air cooling. Please contact the factory for details.
