Liebert has reinvented the double-conversion UPS. The Npower is the result of an international design collaboration and more than a decade of advanced research.
Every aspect of the Npower shows careful design and attention to detail. The rugged powertrain and advanced ActiveStarn.t controls were subjected to computer simulations and thermal analysis to ensure reliable performance in every environment.
Even the physical packaging is uniquely efficient, to make fully configured systems more compact than other products on the market.
Best of all, it’s a Liebert product designed to give the same million-hour critical bus lVITBF as its older brothers.
