Industrial Supplies Resist Noise

Particularly well-suited for use in industrial and commercial settings where harmonic noise interference must be resisted, the MPS series of single- and three-phase power supplies comply with EN50081-1 and EN50082-2 noise specs, have an efficiency of up to 90%, and are said to be unaffected by humidity as high as 90%. The supplies are equipped with a host of protection features, with the units' three LEDs providing a visual indication of proper operation and warning of problems. A built-in battery back-up function also is available. Single-phase supplies are available with a 90-265, 95-132 or 185-265 vac input and 3A, 5A, 10A or 20A output; three-phase units have a 360-520 vac input and 10A, 20A or 40A output. MTBF is >350,000 hours. And all except the 40A unit are 35-mm DIN-rail mountable.
