Specifications
asure AC single phase active electric power which the rated voltage is 220V and frequency is 50Hz.Product overview:
DDS single phase electronic watt-hour meter uses imported specific large-scale integrated circuits and other advanced technology. It can measure AC single phase active electric power which the rated voltage is 220V and frequency is 50Hz. It can measure forward and reverse active power accurately and it calculates accumulatively in the same direction. It can prevent electric larceny at the same time. It outputs heartbeat through optical couple. LED displays electricity consumption,so that it si easy to control.
Features of function:
It conduct Signal sampling from shunt voltage divider. It can drive a stepper motor to let the register calculate the energy degrees cumulatively through the processing of amplification, multiplication, integration, V/F conversion, frequency division, power driver, etc.
Specifications and main technical parameters:
- high precision: error <±1.0%<±2.0%
- high sensitivity: Start current<O.4%Ib
- Wide load: current overload multiple > 12times
- low power consumption : the meter itself consumes < 1W
- High reliability:>100000 hours
- light weight : <O.6Kg
- Starting current : when rated voltage, rated frequency and power factor are1.0, and load current >0.4%1blt, the meter can work properly.
- Creeping:Anti-creep logic circuits
- Reference voltage(V):220
- Basic current: lb(A):1.5(6),2.5(10),5(20),10(40),15(60)
