Murata Power Solution’s DMS-PS-CM Series
night light! These low cost, high-efficiency
power supplies can significantly reduce
long-term electricity costs in low (<5Watts)
to medium (<16Watts) power applications.
All DMS-PSX-CM power supplies fea-
ture universal inputs of 85-264Vac 50/60Hz,
built-in line fuses, and on-board ‘Power On’
LED indicators. At full rated load, hold-up
time is typically 20ms at 120Vac, and 80ms
at 230Vac. All outputs provide indefinite
short-circuit protection and, for added reli-
ability, the main high-current output also
includes overvoltage protection. A rugged,
vibration-proof, chassis mount package
incorporates large, shock-resistant terminal
blocks for all I/O connections.
of high-efficiency, chassis mount AC/DC
power supplies feature low noise (40mV on
main, 8mV on auxiliaries), fully-isolated +24,
+12V, and +5V outputs, making them perfect
for powering today’s complex instrumenta-
tion. A high-current main output is isolated
from the AC line by 3000Vac. In dual- and
triple-output models, the low-current auxiliary
outputs are isolated from the main output by
1000Vdc, and from each other by 2000Vdc,
effectively providing double isolation from the
AC line! This unprecedented isolation elimi-
nates ground loop problems in complex,
multiple-instrument applications.
Full-load efficiencies of up to 80% and
output-power ratings of 5, 10 or 16 Watts,
combine to ensure minimal ac power con-
sumption. For intermittent use or low-power
applications, the 5-Watt model’s no-load
quiescent consumption with a nominal
120Vac input is a mere 0.6 Watts---that’s
nearly seven times less than a standard 4W
