Its completely independent intellectual property rights and minimum size._x000D_ The meter fully complies with the relevant technical requirements of the class 1 single-phase active meter specified by the international standard IEC62053-21. It can accurately and directly measure 50Hz or 60Hz active power consumption from a single-phase AC grid, and can display the total power consumption through the stepper motor type pulse register._x000D_ It has the characteristics of good reliability, small size, light weight, beautiful appearance and convenient installation._x000D_ Functions And Features: _x000D_ 1.35mm standard DIN rail installation, in line with standard DIN EN50022._x000D_ 2. Unipolar width (modulus 18mm), in line with standard DIN43880._x000D_ 3. Display the standard configuration 5 + 1 number (99999.1kWh) through the stepper motor type pulse register._x000D_ 4. Standard configuration of passive pulse output (polarity), long-distance pulse output passive (polarity) can be selected. And easily contact with various AMR systems, in line with standards IEC 62053-31 and DIN 43864._x000D_ 5. When the meter starts measuring, the pulse indicator flashes._x000D_ 6. One-way measurement of single-phase two-wire active power, independent of the direction of the load current trend. Comply with standard IEC 62053-21._x000D_ 7. Standard configuration S type connection, U type connection can be selected._x000D_ 8. Extend the terminal cover to protect the safety of use. State (green) and energy pulse signal (red)._x000D_ 9. Directional measurement of AC active power consumption. The direction in which the load current flows does not matter. Comply with standard IEC 62053-21._x000D_ 10. Direct connection operation, two types of wiring can be selected. The standard configuration is S-type wiring, but U-type wiring is possible._x000D_ 11. Extend the terminal cover to protect the safety of use_x000D_ _x000D_ Size: Approx. 88mm / 3.5in_x000D_ 63mm / 2.5in_x000D_ 75mm / 3in_x000D_ _x000D_ 44mm / 1.7in_x000D_ 45mm / 1.8in_x000D_ 68mm / 2.7in_x000D_ _x000D_ 35.5mm / 1.4in_x000D_ 5mm / 0.2in
