DIN-rail three-phase multifunctional energy meter DSZ12DM-3x80A has passed the EU metrological certification MID certification (0120/SGS0204), with the advantages of compact size, high precision, good reliability, easy installation and so on.
It adopts DIN35mm DIN-rail mounting structure, LCD display, measuring electric energy and other electric parameters, with compound rate metering, electric energy pulse output, power failure key wake-up, automatic power feeding, LCD backlight display and other functions.
With M-Bus interface, it can be connected to the corresponding bus equipment, which is suitable for the occasions with poor wireless signal coverage or no network coverage.
I. Product characteristics
- with DIN35mm rail mounting, width of 4 modules;
- with three-phase power metering, with compound rate metering;
- with LCD display, low power consumption;
- real-time measurement of electrical parameters of electrical energy, such as voltage, current, power, etc.; with passive opto-isolated, electrical energy pulse test output function; with blackout display function, and does not use batteries, with environmentally friendly supercapacitor, without power supply state, LCD can be two weeks.
- has passive photoelectric isolation type, power pulse test output function;
- with power failure display function, and does not use batteries, with environmental protection super capacitor, in the absence of power supply state, LCD can be displayed twice a day for two weeks;
- error message (false), with the current reverse, loss of voltage/phase failure alarm indication function. Loss of voltage/phase break alarm indication function, when the phase is missing or the current direction is wrong “false” and the corresponding phase line will be displayed on the liquid display, at the same time, the LCD backlight will also be flashing with the same frequency;
- can be extended with M-Bus communication interface;
- power is displayed through the display bar flashing to show, the LCD backlight will also flash with the same frequency; · power is displayed through the display bar flashing to show. The power consumption is indicated by a flashing display bar with a frequency of 1000 imp/kWh;
- Second rate switching is realized by applying 230V to the E1/E2 terminals.
