Tripp Lite's Modular E3 Series 3-Phase UPS Systems provide lower input current THDi than competitive models, dramatically lowering installation costs. Generators: with Tripp Lite's Modular E3 Series 3-Phase UPSs, managers can match the KW size of their generator to the kVA of its UPS (referred to as 1:1 sizing or "generator-friendly design"). With competitor's UPS models, managers often have to double the size of the generator to compensate for higher input current THDi (referred to as 2:1 sizing). Cables and Breakers: with less distortion reflected back to the source/input, managers can install smaller sized cables and lower trip-rated circuit breakers.
