Overview:

The YN20 rail type single-phase energy meter is a new type of single-phase two-wire active energy meter with completely independent intellectual property rights, developed by our company using microelectronics technology and imported specialized large-scale integrated circuits, and advanced technologies such as digital sampling processing technology and SMT process. This meter has been tested by the internationally authoritative KEMA laboratory and its performance fully meets the relevant technical requirements of Level 1 single-phase active energy meters in the IEC62053-21 international standard. It can directly and accurately measure the active energy consumption in single-phase AC power grids with a rated frequency of 50Hz or 60Hz. This meter displays the functional battery level on an 8-bit LCD display with a white backlight source; It has the characteristics of good reliability, small size, light weight, beautiful appearance, and easy installation. At present, the patent for this table is under review by the Chinese National Intellectual Property Office.

Characteristics:

35mm DIN standard rail installation, in compliance with DIN EN50022 standard.
Level 1 width (module 17.5mm), in compliance with DIN43880 standard.
Standard 7-bit+1 (9999999.1kwh) LCD display with white backlight source, optional 7+1-bit ordinary LCD display without backlight source (product configuration code SH)
The standard configuration includes passive power pulse output (with polarity) and optional passive motion power pulse output (without polarity), making it easy to connect with various AMR systems and complying with IEC62053-31 and DIN43864 standards.
The dual color LED only displays the power status (green) and power pulse signal (red).
Automatically detect the direction of current flow and display it on the LCD only (when the LCD displays HELP1, it represents the opposite direction of current flow).
Single directional measurement of single-phase two-wire active energy consumption, independent of current flow direction, in accordance with IEC62053-21 standard.
● Direct access type use, with two wiring options to choose from, standard configuration S-type wiring, and optional UX type wiring (product configuration code UG)
Extended terminal cover for electrical safety protection.
