DIN-rail three-phase multifunctional energy meter DSZ14WDRS-3x5A has passed the EU metrological certification MID certification (0120/SGS0314), with the advantages of compact size, high precision, good reliability, easy installation, etc. 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 outage, key wake-up, electricity auto-feeding, LCD backlight display and other functions. It has the functions of compound rate metering, power pulse output, power failure, key wake-up, automatic power feeding, LCD backlight display and so on.
CT ratio setting function can match: 5:5,50:5,100:5,200:5,250:5,300:5,400:5,500:5,600:5,750:5,1000:5,1250:5,1500:5 and so on many kinds of ratio current transformer; There is RS-485 bus interface, can connect the corresponding bus equipment, large current It is suitable for places where direct access energy meters cannot meet the demand and places with poor wireless signal coverage or no network coverage.
With DIN35mm rail mounting, width of 4 modules.
Three-phase power metering with double-rate metering.
LCD display with low power consumption.
Real-time measurement of electrical parameters, such as voltage, current, power, etc..
With passive optoelectronic isolation type, power pulse test output function.
With power failure display function, and does not use batteries, with environmentally friendly supercapacitor, in the absence of power supply, LCD can be displayed twice a day for two weeks.
Error information (false), with current reverse, loss of voltage / phase alarm indication function, when the phase is 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.
Extendable with RS485 communication interface.
The amount of power is displayed by means of a flashing bar with a frequency of 10 imp/kWh.
Various CT variations can be set by applying jumpers.
