Detailed Product Description

  Product brief introduction

This single phase electronic type active energy meter adopts advanced microelectronics technique and SMT manufacturing technology, its performance conforms to GB/T17215-2002 standard. This product is used for measuring single-phase AC active electric energy whose rated frequency is 50Hz or 60Hz. These single-phase active electric energy meters owns many functions as active forward direction and reverse direction electric quantity metering respectively or active forward reverse direction power accumulation metering, also have infrared and RS-485 interface communicating etc and adopt LCD means, hand meter reading device to set power consumption parameter and reading electric quantity, so this product is an ideal metering device for inhabitant to power utilization. Besides, it also owns many advantages as high metering precision ,high sensitivity, reliable performance, wide loadlow power consumption, small volume, light weight, simply operating and easy for installation etc.   Function and features      1. Owning forward and reverse direction metering function, besides, it can accumulate         electric quantity in one same direction, that is, calculation reverse electric quantity into        forward direction.    2. The electric quantity adopts displaying, of which there are five integer-places and two        decimal-place while also can be six integer-place and one decimal-place, its unit is        kilowatt-hour, making record of accumulated total electric power consumption.    3. When electric energy meter is communicated with external equipments, the         communication indicator lamp would be brightened, which stands for that the electric         energy meter stays at communication state.    4. Own passive isolated type electric energy impulse output terminal, the impulse output is         square wave, and the impulse width is not smaller than 80ms±20%.    5. Data programming (RS-485 or infrared programming, setting and meter reading). Able to         set meter on of electric meter (Add)starting count of active electric energy and cipher         etc.  Specification and Technical Data     1. Rated current: 5(20)A ,5(30)A, 10(40)A, 15(60)A    2. Rated frequency: 220V, 230V    3. Rated frequency: 50Hz, 60Hz    4. Accuracy class: class1, class2
