DDS309-DIN-type (DIN) installation of three-phase four-wire electronic active energy meter system I used microelectronics technology and special large-scale integrated circuits, digital sampling processing technology and SMT technology, such as cash technology research and development of three-phase four Line active energy meter. The technical performance of the table in full compliance with GBT17215.321-2008 and ICE62053-21 international standards in a three-phase active energy meter related technical requirements, can be directly and accurately measure the rated frequency of 50HZ or 60HZ three-phase four-wire AC power load Consumption of active energy. The table oil stepper motor pulse counter shows the active power and LCD active power consumption, with good reliability, small size, light weight, beautiful appearance, easy installation and so on.

1,35mm DIN rail mounting, according to DIN EN 50022 standard, or board-type installation (mounting hole center distance 63mm), two installation methods can be arbitrarily selected by the user.
2,10 pole width (modulus 12.5mm), in line with GB / T7121-1993 standards.
3, equipped with a polarity of the passive near-power pulse output port in line with ICE 62053-31 and DIN 43864 standards.
4,5 LEDs indicate the power status of each phase and the short-range power pulse signal as well as the remote power pulse signal.
5, automatic detection of load current flow direction, and instructions (work close to the power pulse signal indicates green, the current direction of the opposite direction of the current)
6, single three-phase measurement of three-phase four-wire active power consumption, and has nothing to do with the direction of the current flow, in line with ICE 62053-21 standard.
7, the choice of two-component measurement of three-phase three-wire active energy or two-phase three-wire active energy.
8, the standard configuration S-type wiring (bottom line, the top outlet), direct access to use, can choose 5 + 1-bit pulse counter display, CT access and PT & CT access use.
