This meter a new generate multifunction Energy Meter, with stable performance, abundant functions and strong anti-interference capacity, as well as meticulous designs in operation convenience and data security. The meter adopts hermetic construction and enclosure, suitable for the application under harsh conditions as alternating high and low temperature and hygrothermal environment. Lead sealing may be applied to the battery holder and programming buttons to facilitate the management by power supply authority.
Large size and wide-angle LCD display, provided with rich status indicators and prompting symbol in Chinese characters, with backlight;
Dual RS-485 communication interface, attachable or far infrared communication interface, with respectively independent channels. Equipped with active and reactive idle contacts electric energy impulse and LED electric energy impulse outputs.
Time-of-use metering on forward and reverse active electric quantity, four-quadrant reactive electric quantity, combination 1 and combination 2 reactive electric quantity; combination mode: arbitrary combination for four-quadrant; the metering will be divided into forward and reverse active electric quantity and inductance-capacitance reactive electric quantity.
Time-of-use metering on forward and reverse active and reactive maximum demand quantity and time of occurrence.
Maximum 8 tariffs, primary and secondary time frames, dual-backup clock, automatic error correction, and maximum 13 months history recording.
Provided with settings for 6 types of data logging load curves, with a capacity up to 4MB.
