Single-Phase Electronic Watt-Hour Meter(ltca3)

Detailed Product Description

Product Brief Introduction
This single phase electronic type active electric 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. This single-phase electronic type active electric energy meter owns many functions as active forward directionreverse electric quantity accumulated metering or active forward reverse power accumulation meteringinfrared and RS-485 interface communicating etc, with characteristics of LCD displaying meanshand meter reading device for setting power consumption data and reading electric quantity, so, this product is ideal metering device for inhabitant power utilization charging. Besides, it also owns many advantages as high metering precisionhigh sensitivityreliable performancewide loadlow power consumptionsmall volumelight weightsimply 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.
