With wide viewing angle LCD display provides a wealth of graphics or text message; the display can be checked by pressing a button, the contents of the display can be configured on demand through the communication port,Backlight LCD is for easy viewing. Support blackouts wake function, wake-up mode can be active via button or non-contact way, the screen display data which can be read directly
2. The communication port include: RS-485, infrared, all ports are independently, comply with DL/T645-2007 and related documents
3. Hourly metering active power forward, reverse active power, reactive power four-quadrant, support a combination of active and reactive power any combination of four quadrants; metering phase of the forward active, reverse active and reactive power quadrant. Measuring voltage, current, active power, reactive power, apparent power and power factor and other network parameters. Measurement accuracy, providing class 0.2S, 0.5S, 1.0, etc. to choose different measurement accuracy.
4. Hourly metering forward active, reverse active and reactive four-quadrant maximum demand and time of occurrence
5. It can store up to 13 months of historical energy and demand record. The data can be used for settlement 3 times a month.
6. Up to 8 tariffs, 2 sets rates schedule standby, clock dual backup automatic error correction. Dual backup data storage, automatic parameter correction. Category 6 data records can be set to load curve, the storage capacity of 2M bytes. Comprehensive event recording type, having openings tamper detection. Recorded and stored voltage quality statistical data for 13 months. Extensive self-test, error correction and alarm functions.
The meter can be wake up by buttons and HHU after power failure, far-infrared meter reading available
7. 10 classes password protection, password locking after several wrong typing, support the single-level password lock function.
8. AC / DC Adaptive auxiliary power supply, priority after power is supplied by an auxiliary power source.
