DATEL Presents DMS-PS-CM Series Power Supplies

DATEL Inc. (Mansfield, MA) announced its new DMS-PS-CM Series of high-efficiency, chassis-mount, ac/dc power supplies, which feature low noise (40mV on main, 8mV on auxiliaries) and fully-isolated +24V, +12V and +5V outputs. The new low-cost, high-efficiency power supplies can significantly reduce the long-term electricity costs in low (<5W) to medium (<16W) power applications.

A high-current main output is isolated from the ac line by 3,000Vac. In dual- and triple-output models, the low-current auxiliary outputs are isolated from the main output by 1,000Vdc, and from each other by 2,000Vdc, providing double isolation from the ac line. Full-load efficiencies of up to 80 percent, and output-power ratings of 5W, 10W or 16W, combine to ensure minimal ac power consumption. For intermittent use or low-power applications, the 5W model’s no-load quiescent consumption with a nominal 120Vac input is only 0.6W.

The DMS-PSX-CM power supplies feature universal inputs of 85Vac to 264Vac, 50Hz to 60Hz, built-in line fuses and on-board power-on LED indicators. At a full-rated load, the hold-up time is typically 20ms at 120Vac and 80ms at 230Vac. All outputs provide short-circuit protection and, for added reliability, the main high-current output also includes over-voltage protection. Additional features include multiple outputs, low noise, low cost, high efficiency, double isolation and rugged construction.

The 5W, single-output, DMS-PS1-CM ac/dc power supplies are priced at $54 in single quantities, and $38 for 500 pieces. Production quantities require six to eight weeks.
