DIN-rail three-phase multi-function energy meter DSZ14DRS-3x80A has passed the EU measurement certification MID certification (0120/SGS0204).
It has the advantages of compact size, high precision, good reliability, easy installation, etc. It adopts DIN35mm rail mounting structure, LCD display, measuring electric energy and other electric parameters, with compound rate measurement, electric energy pulse output, power failure key wake-up, power automatic feed-in, LCD backlight display, etc. It has RS-485 bus mode interface.
With RS-485 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.
- Has DIN35mm rail mounting with 4 module widths;
- hree-phase power metering with compound rate metering;
- LCD display, low power consumption;
- Real-time measurement of electrical parameters, such as voltage, current, power, etc;
- With passive photoelectric isolation type, power pulse test output function;
- With power failure display function, and does not use batteries, with environmentally friendly supercapacitor, in the —- no power supply state, LCD can be displayed twice a day for two weeks;
- Error message (false), with current reversal, loss of voltage/phase break alarm indication function, when — phase missing or current direction error “false” and the corresponding phase line will be displayed on the liquid display, at the same time, the LCD backlight will be the same frequency blinking;
- Expandable with RS485 communication interface;
- The amount of power is displayed by flashing the display bar with a frequency of 10 imp/kWh;
- Second rate switching by applying 230V to the E1/E2 terminal;
