prepaid energy meter

1 LCD Display: can show 6 digits(5 integer and one fraction)

2  With  bi-directional  metering  function  can  accurately  measure  the  electricity consumption of the positive and negative directions, and accumulated energy in the same direction. Have anti-theft function.

4 Main Structures and Working Principle

1 Electronic component is mounted on a printed circuit board (PCB). The upper cover is fixed by screws, which can lead seal. Terminal box cover is fixed with special screw fixation, which can lead seal.

2 Energy meter works for the voltage and current signals via a dedicated line into a

weak signal input to the ASIC complete power measurement, the measured power via V / F transformation, promoting the work of degrees, and the pulse signal sent dedicated circuit for energy meter calibration.

5. Installation

5.1.1 Electric energy meter has been checked and with a lead seal in the factory. Users can install and use without calibration.

5.1.2 The board of meter should be fixed in the solid refractory wall, suggest mounting height is about 1.8m, the air with no corrosive gas.

5.1.3 Electric energy meter wiring connection should be followed to the wiring diagram on the terminal cover, preferably with a copper or copper terminal access.

6.Dimension

Single Phase Static Watt Meter

6 Transport and Storage

1-Energy meter should not be severe impact on transportation and unpacking. According to GB/T 15464-1995 "General Instrument Package technical conditions" requirements, transportation and storage.

2- Energy meter should be stored in the original container, storage ambient temperature of -25 °  C to 70 °  C, relative humidity less than 85%, non-corrosive gases in the air.

3-Storage of energy meter is in warehouse. Placed on the bench, stack height not exceed 5 boxes, after unpacking single Meter the stack height not more than five.

7 Quality Guarantee Period

Since the manufacture date in two years, under the conditions of the user to comply with the requirements of user manual to use and seals intact, Where the quality of cause of failure of the meter, Company will provide free repair or replacement.
