Three-phase electric energy meter LCD Guide

Detailed Product Description

I. Introduction
Of the three-phase active power meter is a rail-type advanced microelectronic technology and SMT manufacturing process of products, the products are used in rated frequency 50Hz (also produce rated frequency 60Hz) of the three-phase AC active energy measurement. The three-phase active power meter with IR and RS-485 port communication function, using LCD display that can be used hand-held meter reading machine set-up and electricity meter reading. Is to achieve the ideal of measuring residential electricity billing meters, also has a measurement of high precision, high sensitivity, reliable performance, load width, low power consumption, small size, light weight, simple operation, easy to install and so on.
The products meet the IEC 62053-21 standard for electronic energy meter of all the technical requirements.
1, measuring three-phase active energy, long-term work without adjustments;
2, three-phase power supply line (three-phase three-wire watt-hour meter in either three-wire line) or two lines (three-phase four-wire watt-hour meter in either two-wire four-wire) power outages, measurement accuracy is not affected;
3, wide operating temperature range;
4, with broken functionality or voltage relative to instruction indicator function;
5, with the reverse direction feature: When the current is reversed, reverse indicator light
6, when the meter when communicating with external devices, communication indicator light, said the state energy meter in communication.1, Rated current: 3 × 1.5 (6) A, 3 × 5 (20) A, 3 × 10 (40) A, 3 × 15 (60) A, 3 × 20 (80) A, 3 × 30 (100 ) A
