Features
DATEL’s DMS-PS-CM Series of high-efficiency, chassis mount AC/DC power sup-
plies feature low noise (40mV on main, 8mV on auxiliaries), fully-isolated +24, +12V,
and +5V outputs, making them perfect for powering today’s complex instrumentation.
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 eliminates 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 consumption. 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 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 feature 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 reliability, 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.
Multiple outputs, low noise, low cost, high efficiency, double isolation, and rugged
construction combine to make DMS-PSX-CM Series AC/DC power supplies the ideal
choice for powering today’s sensitive instrumentation, and any electronic device that
requires a reliable dc voltage!
