DIN-rail mount power supplies meet UL508
24 October 2001
Power Electronics / Power Management
Power-One's W Series of DIN rail-mount AC/DC and DC/DC converters is available at 120 and 250 W with single or dual 24 V and 48 V outputs. Active Power Factor Correction (PFC) is provided to meet European line harmonics standard EN61000-3-2. Typical applications include process control and energy distribution.
Features include efficiencies up to 89%, 85-264 V a.c. input, peak power rating of 150%, and immunity against voltage dips and brownouts. These products operate in ambient temperatures from -40 to +60°C and do not require forced-air cooling. The overall size is 103 x 138 x 114 mm.
Additional standard features include less than 5 A of input inrush current, no minimum load required, operation from 110/220 V battery systems, controlled current limit, and short circuit protection. Optional features include remote programming and screw terminals. Battery charger models are also available with remote temperature control and monitoring.
