Vibration, Pressure 5Hz to 500Hz 2.5G rms (approx.) WR-U SERIES Single and dual output [ 2 YEAR WARRANTY ]
- 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 –25°C to 71°C with no derating required and all models are free-air convection cooled. SPECIFICATION All specifications are typical at nominal input, full load at 25 ° C unless otherwise stated PAGE 1 Data Sheet © Artesyn Technologies® 2000 The information and specifications contained in this data sheet are believed to be correct at time of publication.

Consult factory for details. 6 MTBF figures are based on actual product performance. Consult factory for details.
7 Fixed frequency design provides for easier input filtering and better noise
performance.
8 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.
