R 35mm DIN standard rail installation, in compliance with DIN EN 50022 standard, or front panel installation (installation hole center distance of 63mm), two installation methods can be chosen by the user at will.

R 10 pole width (module 12.5mm), in accordance with JB/T7121-1993 standard.

R 4 rate, can be set for 12 day periods, and the automatic reading date for each month can be set arbitrarily. The single rate function for weekends can be selected.

The R maximum demand measurement function allows for the selection of interval demand (default) and sliding demand, with a demand cycle of 1-99 minutes that can be set. The maximum demand can be automatically or manually reset, and can be freely set.

The R has a built-in clock and maintenance free backup lithium battery, with real-time detection and display of battery capacity. It can store 12 months of battery data, which will be permanently saved after power failure.

R can choose between cyclic display (default) or key by key display mode. The cyclic display period can be set, and up to 48 data items can be displayed in a cyclic manner. The displayed data items can be selected, and the decimal place for displaying electricity data can be set to one or two digits.

The R configuration has polarity passive active power pulse output ports and reactive power pulse output ports, with four output pulse rates of 0.01, 0.1, 1, 10 kWh or kvarh/Pulse, which can be freely set by the user and comply with IEC 62053-31 and DIN 43864 standards.

The R equipment is equipped with far-infrared and RS485 data communication ports for meter setting and reading. The meter setting operation has password protection function. The standard configuration communication protocol complies with DL/T645-1997 standard, and other communication protocols can be selected (please specify when ordering).

R-S type wiring (bottom inlet, top outlet), can be used directly or CT inlet. CT inlet instruments can be set with 27 CT ratios, and the instrument will read directly when set, without the need to multiply by CT magnification.

R direct access instrument display mode 6+1 bit (999999.1) LCD display.

The display mode of the R CT connected instrument is 5+2 digits (only when the CT ratio is 5:5A) or a 7-digit integer LCD display, selected by the set CT ratio.

The R LED indicates the power status, power pulse signal, load current flow direction, current rate status, and data communication status.

Measure the active and reactive electrical energy, maximum demand for active and reactive power, real-time active, reactive, and apparent power, real-time phase voltage, phase current, real-time frequency, and real-time power factor of three-phase forward and reverse, in accordance with IEC 62053-21 and IEC 62053-23 standards.

The R transparent PC material molded short terminal cover is beneficial for reducing installation space and facilitating centralized installation.
