[ 2 YEAR WARRANTY ]
The WR series DC/DC converters accept a wide input voltage range of 9-
18VDC, 18-36VDC or 36-72VDC. A 100kHz switching regulator produces
operating efficiencies up to 86% at full load and as high as 80% at light load. In
the case of duals, full power may be taken from either output. All models will
tolerate a short circuit between positive and negative outputs or between either
output and common indefinitely. Load regulation of ±1%, line regulation of
±0.2%, Pi input filtering and remote on/off control (XC package only) which can
be improvised as an undervoltage shutdown signal, are featured on all models.
Six-sided continuous EMI/RFI shielding is provided in both XC and MP
packages. The operating temperature range is –25°C to +71°C convection
cooled, with no derating required.

Load regulation is measured from full load to 25% full load.
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.
Fixed frequency design provides for easier input filtering and better noise
performance.
In many cases, the isolation specification may be upgraded. Consult
factory for details.
XC case only (single output models): to trim up connect pin 4 to pin 7
through a 10kΩ resistor, or pin 4 to pin 6 to trim down.
MTBF figures are based on actual product performance. Consult factory
for details.
