◈Overall and installation dimension
The three-phase multi-rate watt-hour meter track can be accurately measured active positive and negative direction, with the meritorious record of aximum demand function, voltage, current, power and other electrical parameters in real- time measurement and processing, with time-sharing control, automatic meter reading, the amount of electricity and the need for data storage, energy meter records of the current operational status, event data recorders and other functions,to achieve energy hourly metering and accounting work in an ideal intel l igent instrument. Watt-hour meter using a large-screen LCD display, with far-infrared, RS485 communication interface etc. The instrument for the introduction of advanced ultra-low power consumption LSI technology and SMT process manufacturing high-tech products,Selection of the key components of international ly famous brands of long-l ife devices, with good rel iabi l ity, smal l size, light weight, beautiful appearance, easy instal lation etc.
This product compl ies with IEC62053-21 standard requirements for active power meter, GB / T 15284-2002 special requirements for multi-rate watt-hour meter, JJG596-1999 Electronic Energy Meter Verification Regulation, DL / T 614- 1997 Multi-function watt-hour meter, DL / T 645-1997 Multi-function watt-hour meter communication protocol, "Zhej iang Province, three-phase electronic type (hourly) energy meter technical conditions (for trial implementation)" "Zhej iang Province, three-phase electronic type (TOU) power meter communication protocol conditions (for trial implementation) "(V3.0).
