The R meter cover and wiring terminal cover are made of transparent UV resistant PC material by integral molding, while the meter bottom and wiring terminal seat are made of high-quality rubberwood material that is moisture-proof, flame-retardant, and heat-resistant by integral molding. They have the characteristics of good weather resistance, high rigidity, and excellent insulation performance.

R 6+1 bit (999999.1kWh) LCD display.

R optional built-in maintenance free lithium battery, used for power outage LCD display reading.

The R configuration has a polarized passive power pulse output port that complies with IEC 62053-31 and DIN 43864 standards.

The standard configuration of R LED only has one LED indicating the power pulse signal (red). You can choose to add power status indication (green) and automatically detect the direction of load current flow with LED indication (when yellow is displayed, it represents the opposite direction of current flow). Please specify when ordering.

R can measure single-phase two wire or single-phase three wire active energy consumption in a single direction, regardless of the direction of load current flow, in accordance with IEC 62053-21 standard.

R is directly connected for use. There are two wiring options for single-phase two-wire instruments: 1A type wiring and 1B type wiring. The wiring option for single-phase three wire instruments is 2A type.
