active & reactive power meter

DTS (X) three-phase electronic active & reactive power meterThe DTS(X) three-phase electronic active & reactive combination power meter has been selected with the active and reactive power metering chips which are for special uses, and adopted with the SMT surface mounting and wave-soldering processes for manufacture; the product has the features of electric-larceny proof, high precision, high reliability, high overload, low power consumption, small volume, low weight, etc.; it can be widely used in the metering for the three-phase AC active and reactive power of urban and rural residents, plant enterprises, business, etc., Functions and characteristics: 1. Accurately measure electricity energy with the active & reactive power in the three-phase AC 2. Automatically prevent electricity theft, and the electricity with power in the reverse direction will be calculated into that in the positive direction 3. Broad range, high precision, long life cycle, calibration and maintenance free 4. Automatic inspection for phase voltage, and have the function of indication for phase shortage 5. Automatic inspection for the direction of three-phase current, and have the function for indication of current in reverse direction 6. It can normally work and measure in reverse phase sequence , broken zero wire, power failure in 1 phase or 2 phases 7. Optional display means including measurement instrument, LCD screen and LED digital tube, etc. 8. Optional communication interfaces including RS485 and infrared, etc. to fulfill the meter recording on the field or from the remote location Technical parameters: Standard: GB/T17215-2002 (IEC61036: 2000, IDT) GB/T17882-1999 (IEC61286: 1995,EQV) DL/T645-1997 Precision level: Active power: Level 1 and 2 Reactive power: Level 2 and 3 Reference voltage: 3×57.7V 3×100V 3×220V/380V Current specification: 1.5 (6) A, 5 (20) A, 10 (40) A, 15 (60) A, 20 (80) A, 30(100) A Reference frequency: 50Hz/60Hz Working voltage: 0.8Un 1.2Un Limit working voltage: 0.7Un 1.9Un Working temperature : -20°C +55°C Limit working temperature:-35°C +65°C Power consumption: Voltage loop: ≤1W, 5VA Current loop: ≤1VA (1b) Life cycle: >15 years Pulse output: Photoelectric isolation-type output without source ,with the pulse width for 80mS±5mS Telecom regulations: DL/T645-1997, regulations in various provinces, cities and regions or customized as required by the customer Dimensions: 240×140×76 mm(L×W×H)
