XP Power announced the DTE series of encapsulated single output dc/dc converters. The series comprises three ultra-wide input voltage range models offering 20 (DTE20), 40 (DTE40) and 60 W (DTE60) output power. The units are available in either a chassis mount or a DIN rail format, offering flexibility to the designer of the end product. The fully encapsulated package also helps protect the converter from environmental factors often found in industrial applications in addition to aiding heat dissipation.
The converters feature typical efficiency in the range 89 – 92%, run cooler, and consume less power compared to other less efficient converters on the market. The 20-W DTE20 model measures 3.78 x 2.13 x 0.92 in., the 40-W DTE40 is 4.41 x 2.51 x 1.01 in., and the 60-W DTE60 model measures 4.41 x 2.67 x 1.50 in. Two 4:1 input voltage range options are based around nominal 24 (9 – 36) and 48 (18 – 75) Vdc. Tightly regulated single output voltage options of 5.1, 12, 24 or 48 Vdc are available across the range, and provides isolation rated at 2,500 Vdc for 60 s.
The DTE series accommodates operating temperatures over the extended industrial range from ‒40°C to +85°C. Full power is available up to a minimum of +70°C depending on the model. Compliance to the international safety specification for IT equipment UL/IEC 60950-1 is standard and all converters meet the EN55022 Class A limits for both conducted and radiated emissions without the need for any external filtering components.
Protection features such as short circuit, output overload, input under voltage lock-out and output over voltage and a remote on/off capability come standard in the series. Front mounted input and output screw terminal connections provide ease of installation.
