The UWS series of 50-W isolated dc/dc converters are available in either through-hole or surface mount configurations. Meeting the DOSA standard for sixteenth brick dimensions of 1.31 x 0.91 x 0.36-in., they accommodate the 4:1 input range of +18 to +75 Vdc around a nominal 48 Vdc. Input to output isolation is rated at 2,250 Vdc.
The dc/dc converters feature three models with outputs of 3.3, 5 or 12 Vdc. Up to 54–W output is available without forced air cooling. The 12–Vdc unit suits regulated intermediate bus applications. The outputs are regulated to within ±0.125% across all load conditions. The outputs may be trimmed ±10% for the 3.3 Vdc model, or +10% to –20% for the 5- and 12-Vdc models. The operating temperature extends from –40° to +85°C. (Contact company for price and availability.)
