progressive rectifier start up; • start up delay function, to restart the rectifiers when mains power is restored. PEAK SHAVING FUNCTION Thanks to the possibility to set the maximum input power (kW or kVA), NextEnergy can be installed into AC supply systems with limited power availability such as a diesel generator or contractually reduced power sources and then supply the additional power required using the batteries (Peak Shaving function). NextEnergy offers 3 peak shaving operation modes: • Static: the NXE input power is programmed at commissioning time; • User Remote control: the user decides...

as business demands grow: • Parallel configuration up to 8 units NextEnergy UPS can be connected in parallel with up to 8 units to increase the capacity or add redundancy (N+1). Parallel configuration with common or separated battery is possible. • EFFICIENCY CONTROL Mode (ECM) Considering that a typical UPS load can vary from 20% to 80%, the ECM function optimises the operating efficiency of a parallel UPS configuration according to the power absorbed by the load: in case of low load, it sets some UPS in “freeze” mode, ensuring redundancy and a working point of the “live” UPS in the higher efficiency...
