major function

After a power outage, the display can be awakened through buttons or handheld devices, and far-infrared meter reading is possible.

● Big 8 rates, rates can be set, two sets of time periods for primary and secondary, dual clock backup, intelligent automatic error correction, and can record up to 13 months of historical records.

Dual RS-485, adsorption type, far-infrared communication interface, channels are independent of each other and do not affect each other. Support carrier communication function (optional).

Four channels of air contact power pulse and LED power pulse output.

● Time division metering of forward and reverse active power, four quadrant reactive power, combination 1, and combination 2 reactive power can be set, with any combination of four quadrant reactive power; Measure the positive and negative active and capacitive reactive power of phase separation.

Record various events such as voltage loss, full voltage loss, current loss, full current loss, voltage qualification rate, reset, clearing demand, programming, timing, power on, overvoltage, reverse phase sequence, and cover opening.

Time division measurement of high demand and occurrence time for active and reactive power in both forward and reverse directions.

● Large screen, wide-angle LCD display, equipped with various status indicators and Chinese character prompts, with LCD backlight display.

6 types of data recording load curves can be set, with a capacity of up to 2M bytes.

● Dual backup data storage, with self checking and error correction functions, with internal card error, clock error, voltage reverse phase sequence, loss of voltage, overvoltage, loss of current, and battery undervoltage fault alarm capabilities.

Suitable for power plants, substations, and various enterprises and institutions that require high reliability and high stability electricity metering.
