summary
ddsf193 single phase electronic multi rate watt hour meter is a new generation of electric energy metering products developed by our company in accordance with the relevant technical specifications of national power grid corp. this product uses a large scale integrated circuit and smt production process, with electric energy measurement, data processing, real-time monitoring, automatic control, information exchange and other functions. the main performance index of electric energy meter with gb/t 17215.211 - 2006 "ac measuring equipment general requirements, tests and test conditions - part eleventh: measurement equipment," gb/t 17215.321 "- 2008 ac measuring equipment - part twenty-first: particular requirements for stationary power meter (1 and 2)," gb/t 15284-2002 "multi rate electric can form special requirements and dl/t 614" - 2007 "multi-function meter", dl/t 645 - 2007 "multi function watt hour meter communication protocol" standard requirements.
main features
■the design and construction of the electric energy meter can ensure that it does not cause any danger under the rated condition；
■the utility model is characterized in that the utility model has the functions of time-sharing measurement, and the active electric energy is accumulated and stored in total, sharp, peak, flat and valley electric energy according to the corresponding period
■with two sets of rate period, can be automatically converted at the agreed time; each rate to support the 4 rates
■with far infrared communication and rs485 communication function
■can be displayed through the key cycle, peak, flat, valley power and current, on january - the cumulative total electricity consumption in december and the rate of electricity consumption, convenient meter reading, power display as a 6 bit integer, the 2 decimal
record the total amount of 12 settlement days, and can be copied by infrared and rs485 interface
■record the total number of school hours (excluding broadcast time), the last 10 times, the operator code
