D-Series 30-40 kVA By drawing near unity power factor from the input current the D-Series UPS system maximises the usable power from your power supply and reduces your operating costs.   A UPS system with Unity Power Factor   Utilising transformer-free technology the D-Series MPR draws 20% less input current than a standard UPS system; this has multiple benefits including reducing switchgear ratings and cable sizes required, decreasing generator ratings and maximising the usable power from your supply. A UPS system that addresses today's concerns   With demand for power a limiting factor in many areas of the UK the D-Series UPS system helps you make the most of what you have. In addition it offers superb energy efficiency of up to 98% helping you to further reduce your operating costs over the life of your UPS system.   A UPS system with low Total Harmonic Distortion   The D-Series UPS system has a THDi of less than 3%. Using a UPS system with such a low THDi markedly improves the quality of your power upstream; reducing the harmonic load on your whole building.     The D-Series UPS system has many innovative, time saving, space saving and money saving features including: Near unity input power factor (>0.99); reduce operating costs Transformer-free technology; smaller footprint Low THDi (<3%); improves power quality Parallelable up to 8 units (as standard); future-proof UPS system Output power factor of up to 0.9, lagging and leading LIFE.net compatible; remote monitoring & diagnostics Innovative design reduces MTTR; maximises availability		Catalogue
