The UPF300 series is very similar to the UP300 series. The major difference is that the UPF300 series includes active Power Factor Correction (PFC), which improves input power factor to better than 0.98 and reduces input current line harmonics below the limit required to meet the applicable European directives. The physical dimensions of the two series are generally the same; however, certain models may require additional heat sinking for low voltage, high current outputs. The UPF300 is one of the flexibility series. In addition to the popular models listed on this sheet, hundreds of potential other modified standard models are available that include full safety agency approval and do not require any Non-Recurring Engineering (NRE) charge. Prototype delivery is typically just a few weeks. Flexibility options include a cover, power fail/power good signal, and an isolated V2 output. Output voltage options are given in the table below. Full custom models are also available. Please contact the factory for details. Available Models Notes: 1 At least 20% of maximum output current is required to maintain stated regulation. 2 Convection cooling 3 Forced air cooling 4 Peak output, 30 sec max 5 The UPF300 series allows very fast flexible modified standard designs within these parameters without non-recurring engineering charge and while retaining safety agency approval.
