RS485 Modbus Three Phase Energy Meters , Electronic kWH Meter With CT operated
Product Description
Model YEM021GC three phase three wire electronic DIN-rail active energy meter,LCD display.
The meter is used to measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net.
The features of small size & DIN-rail mounting make it suitable for installation in distribution boards and small standard enclosures.
The meter is widely used in the office buildings, shopping malls, residences, airports and metro,etc.

Competitive Advantage
1. 35mm standard DIN rail installation,complying with standard DIN EN50022.Or front board installed (mounting holes center distance 63 mm), users can choose any one by themselves.
2. Seven poles width.
3. May select 6+1 digits display (999999.1kWh) or 5+2 digits display, it can be arbitrary set by users from far infrared or port of RS485 data communication.
4. Standard configuration one port of pulse output passive (polarity),may select increase a distant port of pulse output passive (nonpolarity),complying with standard IEC62053-31 and DIN 43864.
5. LED indicates respectively power-supply,impulse,and communication,etc.
6. Automatically detect the direction of the trend of load current. If the LED “REV” lights that means the load current is reverse.
7. Single direction three components measure three phase three wire active energy consumption.It is nothing with direction of the flow of load current,complying with standard IEC62053-21,IEC62052-11.
8. Direct connect operation or through CT or PT & CT.
♦Standard configuration short terminal cover, which is helpful to reduce installation space and make it convenient to install;May select extended terminal cover.
