APPLICATION
7 Module, three phase four wire active electronic DIN-rail watt-hour meter.
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 makes it is 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.
| FUNCTIONS AND FEATURES |
| ?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. |
| ?Seven module 125mm width. |
| ?Cyclometer 5+1 digits display (99999.9kWh),or 6+1 LCD display with backlight,or LED display. |
| ?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. |
| ?LED indicates phase-line,impulse,reverse,etc. |
| ?Automatically detect the direction of the trend of load current. If the LED "REV" lights that means the load current is reverse. |
| ?Single direction three components measure three phase four wire active energy consumption. It is nothing with direction of the flow of load current,complying with standard IEC62053-21,IEC62052-11. |
| ?May select two components measure three phase three wire active energy or two phase three wire active energy. |
| ?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. |
| OPTIONAL FUNCTIONS |
| ?Anti-tampering functions are available; |
| ?Optical port or far infrared port, RS485 (Modbus) output interface (optional) enable remote data transfer, remote -control reading and parameter setting; |
| ?Multi-tariff is available (optional TOU or step tariff); |
