Product Overview
The Flatpack S 48/1800 HE (part number 241122.125) delivers 1800 W of regulated output power with up to 37.5 A at the adjustable 43.5-57.6 VDC output window. Sharing the same 72 x 41.5 x 217 mm, 850 g package as the 1000 W variant, it raises output to 1.8 kW at 96% peak efficiency.
Input is 85-305 VAC at 9.9 A RMS with power factor above 0.99 at 50% load and above. The module operates from -40 to +85 degC, so a single module family covers outdoor cabinets, telecom shelters and industrial sites across extreme climates.
Like its 1000 W sibling, the module holds DNVGL-CG-0339 marine type approval and integrates with Flatpack S power systems and Smartpack controllers for parallel, supervised operation in 1U-2U system shelves.
