DDSF169 single-phase electronic multi-rate energy

Aplication: Type DDSF169 single-phase electronic multi-rate energy meter is a new generation of product, which is developed lately by absorbing the opinions from the experts and majority of power users, as well as foreign new technology. The product meets the requirements of GB/T17215-2002 (rade 1 and 2 static AC active watt hour meter) and GB/T15284-2002 multi-rate (time sharing) watt hour meter. Expect for the fundamental functions of time sharing measurement, it can still be provided with other additional functions(such as maximum demand,infrared meter copying a-an string ,etc) to meet the requirements of different users.Maincharacteristics: 1.Chips,LCDandcrystaloscillatoradoptindustrialproducts,haveLongservicelifeandexcellentperformance. 2.Highintegration,simpleexternalcircuit,rationallayout,goodoverallperformance,smallsize,easyinstallation. 3.Haveastronganti-interferenceandhighvoltagestamping,wideoperatingvoltagerange. 4.Protectivefunctionwithpassword. 5.Functionforprotectingagagingstelectricity-theftwiththewarningdisplayofelectricity-theft.Technical indes:1.Error of day timing: ≤0.3;tempaerature factor ≤±0.1s/(d.°C) 2.Operating voltage range:70% 120% rated voltage 3.Error of collecting signal: ≤1×10-5 4.Power consumption:1W 5.Service temperature: -25 +55°C 6.
