RUW15 Series
Isolated Ultra-Wide Input DC/DC Converters
FEATURES
„ UL 60950 recognized for reinforced
insulation pending
„ High transient voltage withstand capability
„ Ultra wide input voltage range of
16-160VDC
„ Externally settable hold up time with
additional capacitor
„ DC OK/Power Fail signal
„ Short circuit protection
„ Over Temperature protection
„ Over voltage protection
DESCRIPTION
The RUW series is particularly suitable for use
in applications in railway, industry or telecom-
munication where variable input voltages or
high transient voltages are present. With an ultra
wide input voltage range of 16-160VDC, the
RUW series is capable of withstanding surges
from 24,36,48,72, 90 and 110V systems, largely
eliminating the requirement for input protection
circuitry.
Optional features include a Power Fail/DC OK
signal and circuitry to facilitate long hold-up times
with a small external capacitor across ±Vint pins.
