WR-U SERIES
Single and dual output
• 30 Watts output powe r
• UL approve d (48V input mode ls )
• 2:1 input range
• Efficie ncy to 86%
• Is olate d 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.

Nominal input 12, 24 and 48VDC.
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.
EXTERNAL OUTPUT TRIMMING
Output can be externally trimmed
by ±10% using either method shown below.

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. Consult factory
for details.
