Single-phase DDS833 electronic electrical energy meter
Application:
Series electronic single-phase electric meter is the most advanced static electronic 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 accumulates in one direction. The test signal is isolation on flash light, so it could be managed very easy.
The quality technical norm of the products is accordance with the GB/T17215-2002 national standard and IEC 1036 international standard.
Principl
The meter samples the voltage and the current at the voltage divider and the current divider built in the meter. These samples are went to the amplifier and multiplier, output of the multiplier is processed by the integrated circuit V/F conversion, frequency divider, power drive circuits to provide plus to drive step motor and mechanical register to accumulate customer's electrical energy consume.
Technical indes:
High accuracy: Error<+(-)1. 0% 1class(<+(-)2. 0% 2class)
High sensitivety: Initial staring current<0. 4% 1b
Range of large load: Current overload ratio>6
Low power consumption: Consumption of meter itself<1w
High reliability: MTBF>105 Weight: <0. 6kg
Starting current the meter can work correctly at rated voltage, rated frequency, when load current Larger than 0. 4%Ib. (Power factor: 1). Running with no-load.
The meter use logic circuit to anti-creep |
