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
