| Application: Series electronic single-phase electric meter is the most advanced static electronc meter in China. The meter designs use large-scale integrated circuit, high reliability step motor, it can meter the AC single-phase active energy(voltage rating: 220V; Frepuency 50Hz), positive and negative two directions and accmulates in one direction. The on flash light, so it could be manged very easy. The puality technical norm of the products is in accordance with the GB/T17215-2002 national standard and IEC61036 intemational standard. Principle: The meter samples the voltage and the current at the voltage divider buit in the meter. These samples are went to the amplifier and multiplier, output of the multier is processed by the integrated circuit V/F conversion, frepuency divider, power drive circuits to provide plus to drive step motor and mechanical register to accumulate custmer's electrical energy consume. Technical indes: High accuracy: Error<1.0%1Class(<2.0%2class) High sensitivety: Initial staring current <0.4%Ib Range of large load: Current overload ratio>6 The temperature rage: The normal temperature of work: -10-45The extreme limit temperature: -40-65 Low power consumption: Consumption of meter Itself <1W High reliabilty: MTBF>105 Weigh: <0.6kg Starting current the meter can wok correctly at rated frequency, when load current is Larger than 0.4%Ib. (power factor: 1), Running with no-load The meter use logic circuit to anti-creep. |
