hDTS5558 Three Phase Oem Energy Meter On Saleree phase electric kWh energy meter
DSS5558/DTS5558 series three-phase three-wire/four-wire static active energy meters are based on advanced SMT technology and LSI, and adopt modern microelectronics, computer technologies and modern management methods. The products have the characteristics of high reliability and high accuracy. The technical indexes of meter conform to the standards of IEC61053 ”Classes 1 and 2 Electricity metering equipment (a.c.) Particular requirements Part 21: Static meters for active energy”. The product can measure accurately the positive (reverse) active electrical energy of three-phase electrical net.
1.1 Operating principle
Electric circuit principle:Made of measuring unit and data processing unit, and has the characteristics of high reliability, high accuracy and low consumption. Meter adopts three-phase power supply; it can operate normally at the time of only two-phase supplying power (three-phase and four-phase, only one-phase supply power). After sampling voltage and current, the energy consumed by user is changed to signal, then is sent to amplifier and multiplying unit, product signal switched by integral and V/F, output pulse signal by fractional frequency and power drive, and then bring along stepper register to accumulate energy.
