Electric Meter

DDS450 single-phase static watt-hour meter is designed for measuring active energy in single-phase alternating current power grids by connecting up resident power supply system.,It complies with the standard IEC 61036 and has high measurement accuracy. The meter is ISO9001 certified and the design can be tailored to different customer requirements. The meter has high reliability and long service life by adopting large-scale integration (LSI) and surface mounting technology(SMT) as well as international brand and long-life key components. The meter is provided with pulse output, which makes remote control and locale consumption monitor possible. The is a safe and optimized solution designed for the needs of deregulated energy market and automatic meter reading. Basic functions Energy display by register or LCD Bi-directional active energy measurement Operation indicated by pulse LED So output with optical isolated output transistor corresponding to DIN 43864 Optional functions Reverse indicator: An LED indicator will be on when the current is reversed Anti-tamper in condition that load is connected between the line and the earth Entirely closed register HF magnet immune register Reversal preventing register Transformer connection Technical data Applicable standard Service lifetime Accuracy class Working temperature Working voltage range Power consumption Over Voltage protection IEC 61036 -2000 10 years Class1, Class2 -30°C +65°C 0.7 1.2Un Less than 0.7W or 6VA 12kV Specifications Rated Voltage 110V,120V,220V,230V,240V Reference frequency 50Hz or 60Hz Basic Current(Maximum Current) A 2.5(10) 2.5(15) 5(20) 5(30) 10(40) 10(60) 20(80) 10(100 Note: Other voltages between 100 and 500V are also available.
