PMDY330 three-phase rail mounted electric energy meter

1、 Overview
The PMDY330 DIN rail mounted three-phase electronic active energy meter is a three-phase active energy meter developed by our company using advanced technologies such as microelectronics technology and specialized large-scale integrated circuits, digital sampling processing technology, and SMT technology. The technical performance of this meter fully complies with the relevant technical requirements of the Level 1 three-phase active energy meter in the IEC 62053-21 international standard, and can directly and accurately measure the consumption of active energy by loads in a three-phase four wire AC power grid with a rated frequency of 50Hz or 60Hz. This meter is equipped with a 7-digit LCD display to show functional battery levels, and has the characteristics of good reliability, small size, light weight, beautiful appearance, and easy installation.
2、 Functional Features
35mm DIN standard rail installation, in compliance with DIN EN 50022 standard, or front panel installation (with installation hole center distance of 63mm), two installation methods can be freely selected by the user.
10 pole width (module 12.5mm), in compliance with GB/T7121-1993 standard.
7-digit LCD display.
The equipment is equipped with a polarized passive short-range electric energy pulse output port that complies with IEC 62053-31 and DIN 43864 standards.
Five LEDs respectively indicate the power status of each phase, as well as the short distance power pulse signal and remote power pulse signal.
Automatically detect the direction of load current flow and indicate it (when the power pulse signal at close range indicates green during operation, it represents the opposite direction of current flow).
Single directional three element measurement of three-phase four wire active energy consumption, independent of the direction of load current flow, in accordance with IEC 62053-21 standard.
● Can choose to measure three-phase three wire active energy or two-phase three wire active energy with two components
Standard configuration S-type wiring (bottom in, top out), for direct access use, with the option to display 5+1-bit pulse counters, CT access use, and PT&CT access use
● Optional RS485 communication function
