| WR-U SERIES Single and dual output * * * * * 30 Watts output power UL approved (48V input models) 2:1 input range Efficiency to 86% Isolated outputs The WR-U series DC/DC converters accept a wide input voltage range of 9 to 18VDC, 18 to 36VDC, and 36 to 72VDC. A 100kHz switching regulator produces operating efficiencies as high as 86% with output loads as light as 25% of full load. These 30 Watt models provide for remote sensing, input/output isolation of 500VDC minimum, and short circuit protection. The WRU Series incorporates six sided continuous EMI/RFI shielding. The "U" package measures 2.56 x 4.56 x 0.83 inches and is PCB mountable. Other pertinent specifications include: overvoltage protection on all outputs, operating temperature range of -25C to 71C with no derating required and all models are free-air convection cooled.

Maximum at full load. Measured from high line to low line. Measured from full load to 0.25% full load. In many cases, the isolation specification may be upgraded. Consult factory for details. MTBF figures are based on actual product performance. Consult factory for details. Fixed frequency design provides for easier input filtering and better noise performance. Standard specifications are conservative and can be optimised for specific applications. In particular, converter start-up at lower than specified temperature, wider input voltage range and output voltage adjustment are all relatively simple modifications to the standard product.
