PDM-803DL three-phase power rail energy meter factory direct Emil

PDM-803DL three-phase energy meter rail Emil electricity factory direct rail PDM-803DL three-phase power meter factory direct Emil ADL300-EC rail meter ADL300-EC rail meter apply to the frequency 50HZ or 60HZ active energy measurement, suitable for an ambient temperature of -10 ℃ ~ 50 ℃ relative humidity less than 85% of the working conditions. Structural characteristics and working principle of the meter power measurement using microelectronic technology, energy meter sampling signal voltage obtained by the voltage divider, shunt current sampling signal obtained by the multiplier to obtain current and voltage signals and then the frequency conversion to generate a frequency and voltage and current proportional to the product of counting pulses by dividing the drive motor to drive up into the counter measure electrical degrees. Meter using fully shielded, hermetically sealed structure, with good resistance to electromagnetic interference, low self-consumption, energy-saving, high-precision, anti-theft, high overload, long life and other characteristics.
