Perfect for Powering Sensitive Instrumentation
DATEL's new DMS-PS-CM Series of AC/DC instrumentation power supplies are ideally suited for driving modern transducers, digital panel meters, operational amplifiers, and data-acquisition components in complex, multiple-instrument applications. DMS-PS-CM's accept universal ac inputs (85-264Vac @ 47-63Hz) and deliver +5Vdc, +12Vdc and/or +24Vdc outputs from single, dual or triple-output configurations. They feature impressively low output noise (40mVp-p on the main output, 8mVp-p on the auxiliary outputs) and high levels of I/O isolation.
See the block diagram. A modern, high frequency, switching regulator is used on the main output to provide full-load efficiencies as high as 80% for single-output models. The high-current main output is isolated from the ac line by a minimum 3000Vac. For dual and triple-output models, the lower-current auxiliary 5V outputs are isolated from the main output by 100Vdc . . . effectively providing double isolation from the ac line! This unprecedented level of isolation not only increases fault tolerance, it easily eliminates ground-loop problems in multiple-instrument applications.
The additional isolation and the extremely low noise on the auxiliary outputs (8mVp-p) are achieved by using a second DC/DC converter, a low-drop-out (LDO) linear regulator and on-board capacitive filtering on each output.
High Efficiency = Low Operating Costs
See the table below. The DMS-PS-CM's cascaded design approach maintains impressive efficiency. Additionally, for optimal energy savings, users can select the 5, 10 or 16-Watt model that best matches their load requirement. You no longer have to specify a 25-Watt AC/DC power supply to drive a 4-Watt load.
These high-efficiency power supplies can significantly reduce long-term electricity costs. In typical intermittent-use applications, the 5-Watt DMS-PS-CM's no-load power dissipation is less than 1 Watt . . . that's 1/4 of the power used by a 4W night light!

Rugged Construction . . . Wide Temperature Range
DMS-PS-CM power supplies feature built-in line fuses and on-board "Power On" LED indicators. Under full-load conditions, hold-up time with a nominal 12OVac input is 20ms, rising to 80ms at 230Vac. All outputs provide continuous short-circuit protection, and the high-current main output also provides output overvoltage protection.
DMS-PS-CM Series power supplies employ pre-assembled, epoxy-encapsulated power modules that are attached to a rugged, vibration-resistant, chassis-mount package. All input and output connections are made via heavy-duty, shock-resistant terminal blocks.
Designed for demanding industrial applications, all models deliver full rated power at ambient operating temperatures from 0 to +50 deg C without supplemental airflow. With 50% linear derating, the range is a wide -25 to +70 deg C.
