Details Apex: ADVO401The Apex Domestic Voltage Optimisation unit intelligently monitors all parameters relating to your domestic electrical system and delivers optimum performance for voltage dependent loads. All domestic electrical equipment is designed to operate with a range of 207V and 253V, when the supply voltage exceeds 220V waste is generated as both heat and vibration. The Apex VO unit measures incoming and outgoing supply voltage, load, current and temperature to provide the optimum voltage supply to appliances in your home.Product Benefits:Reduces energy usage on voltage dependent loadsReduces carbon footprintContributes to Government funded targetsCustomer savings start immediatelySimple to installSubstantially extends the life expectancy of appliances and lightingReturn on investment (ROI) typically 2 to 2 yearsTechnical Characteristics:Input voltage : 216V-253VFrequency : 50Hz/60Hz +/- 3 HzCurrent Rating : 40A or up to 60A continuous ratingsInsulation Class : BS2757E (120 C)Max Operating Altitude : 1000mHumidity : 75%Ambient Temp : -10 C to +40 CLow Voltage Directive (72/23/EEC)EMC Directive (89/336/EEC)Machinery Directive (89/392/EEC)Efficiency : >99%Dimensions(mm) : 210h x 410w x 140d
