The "Haosheng" brand DTS1332 three-phase electronic energy meter is a new type of instrument manufactured using a wellhead specific large-scale integrated circuit, 16 bit A/D conversion, digital multiplier, digital sampling processing technology, and SMT process, based on the actual power consumption of industrial users. This meter uses a dedicated single integrated metering module to accurately measure the active energy of three-phase forward and reverse directions. Measurement errors have excellent long-term stability. Choose high-quality tantalum capacitors with long service life. This prevents measurement errors and electricity theft caused by phase sequence errors, current reversal, voltage and current phase differences, voltage line disconnections, and neutral line disconnections during the use of the three-phase system. It complies with GB/T17215-2002 IEC1036； The 1996 standard specifies various requirements for three-phase electricity meters. The main purpose is to measure three-phase active or reactive energy with a rated frequency of 50HZ. It has good anti-interference, low power consumption, high precision, anti-theft, wide range, long life, phase failure indication function, and so on.
