KUIE15 Series AC-DC Power Supplies for Industrial Applications

This 15-watt AC-DC power supply for industrial applications accepts a universal 85 to 264V AC input with a frequency ranging from 47 to 63 Hz. The KUIE15 is available as a 1 x 1.5 x 0.8-inch PC mount, DIN rail or enclosed unit. Features include adjustable output voltage, 3,000V AC reinforced insulation, efficiency up to 89 percent, low standby power, low leakage current and an internal EN 55032 Class B filter. Operating altitude is 5,000 meters. The unit protection Class II meets the IEC/EN/UL 62368-1 safety standard and offers built-in overcurrent, over voltage and short circuit protection. KUIE15 complies with RoHS and REACH regulations.
