TECHNICAL DATASHEET Rev. C XAIS3657 280W AC/DC High Efficiency Power Supply 100-140 VAC Input 28VDC Output at 10A Small 3.5” x 5” x 2” Aluminum Case FEATURES 91% Efficient at Full Load Active Power Factor Correction Low THD Output Short Circuit and Over Current Protection Conformal Coated ISO9001 Compliant UL 1029 R/C FCC Part 15-B Class A Emissions EN 61000-4-5 Surge Immunity EN 61000-3-2 Harmonic Currents 100% Burn-in DESCRIPTION The XAIS3657 AC/DC power supply provides 280 watts of output power and has an input voltage range of 100-140VAC with a 28VDC single output. This supply is housed in a small 3.5” x 5” x 2” aluminum case and features 1600VAC I/O isolation, high efficiency up to 91% at full load, and active power factor correction. This model also has over current and short circuit protection and is 100% burned-in. The XAIS3657 series was designed to be used in the industrial or commercial, indoor and outdoor lighting market. Some applications include lighting for parking lots, roadways, tunnels, warehouses, walkways, billboards, and garages. It can also be used for entertainment lighting applications such as moving heads, scanners, spot and wash lights, and digital projection. 04/06/2011 Wall Industries, Inc. 5 Watson Brook Road Exeter, NH 03833 603-778-2300 www.wallindustries.com Fax 603-778-9797 Page 1 of 7 WALL INDUSTRIES, INC.

TECHNICAL DATASHEET Rev. C XAIS3657 DESIGN CONSIDERATIONS Over Current Protection The converter is protected from short circuit and over current conditions. Upon sensing a short circuit or an over current condition the converter will immediately shut off, and after a short delay try to restart. This is called a ‘hiccup’ mode and this mode will persist until the short circuit or over current condition is removed. Over Temperature Protection The converter is NOT protected from over temperature conditions. Exceeding the maximum rated case temperature may cause permanent damage to the unit. Fusing The input to the converter is protected with a UL R/C fuse. This fuse is NOT user replaceable.
