The Centurion Dual series has been specifically designed to accept a broad range of worldwide mains utility supplies supporting both high-voltage and low-voltage environments. It automatically accepts two input ranges of 88 to 144Vac and 176 to 288Vac. The output is precisely regulated and sustained even at full load. Galvanic isolation is provided via an isolation transformer to isolate the output from the AC input. The UPS provides full isolation and complete common mode noise rejection for connected equipment.
