Model: ADW300W series.
Communication mode: 4G LoRa WiFi wireless metering instrument is mainly used to measure the three-phase active energy of low-voltage network, with the advantages of small size, high precision, rich functions, etc., and there are many communication methods to choose from, which can support RS485 communication and Lora, NB, 4G, WiFi and other wireless communication methods, and increase the current sampling mode of the external transformer, so as to facilitate users to install and use on different occasions. It can be flexibly installed in the distribution box to realize the needs of sub-item power metering, operation and maintenance supervision or power monitoring for different areas and different loads.
Introduction to wiring:
The ADW300, ADW300-HJ and ADW300W can all be connected by three-phase four-wire current transformer, three-phase three-wire through current transformer, three-phase four-wire through voltage and current transformer, and three-phase three-wire through current and voltage transformer. When using three-phase three-wire access, it is necessary to modify the line system of the instrument by pressing the button or the corresponding debugging software.
Here are a few things to keep in mind:
1 ADW300W external transformer is red and white wires, red connected to the instrument IA*, IB*, IC*, white connected to the instrument IA, IB, IC;The ADW300-HJ external transformer is red and black wires, red connected to instrument IA*, IB*, IC*, and black connected to instrument IA, IB, IC;
2.ADW300W or ADW300-HJ both use their own Class MA transformer, and it is strictly forbidden to connect to the ordinary 5A or 1A output transformer, otherwise it will cause damage to the instrument
3.ADW300W or ADW300-HJ When wiring, the transformer terminal is forbidden to be shorted and grounded, otherwise it will cause inaccurate metering or meter damage;
4.When the ADW300W or ADW300-HJ is used to measure the secondary line of the field transformer, the built-in transformer of the instrument should be kept at a distance (greater than 30cm) from the primary side transformer in the field to avoid interference.
