Introduction
RS485 Single/Three-Phase Electronic Energy Meter using long-life, highly reliable electronic components, resulting in long life and high reliability.Support M1 card swipe card recharging, this function is optionalFeatures of product
Shunt metering, shunt control
There are 6 types of DDZY1755 series meters: single metering single channel control, single metering dual channel control, single channel metering three way control, dual metering dual channel control, dual metering three ways control, three ways metering three ways control
Remote monitoring and collection
It can remotely monitor the total electricity consumption, current current, voltage, power, power factor and other parameters of the meter.
Swipe card recharging function
Malignant load limitation
The meter has segmented resistive load identification and limit function
Power protection function
In the emergency state, the power-saving function can be activated to ensure normal power supply without interference.
Delayed power off function
In order to avoid power outage during the peak period of power consumption, you can set the power-off time and continually charge the electricity during the peak period of power consumption.
Support multiple communication methods
Support RS485/MBUS, LORA, NB-IOT and infrared communication methods.
Product features
1. LCD digital display: total power, 6-digit integer + 2-digit decimal (999,999.99kWh).
2. Accurately measure the forward and reverse active power, the reverse power is included in the total power, and the reverse indicator light indicates.
3. Three-phase meter for phase loss measurement, LED alarm indication when phase loss, any phase or any two phases are powered off, the measurement accuracy is not affected.
4. R5485 serial port: DL/T645-2007, DL/T645-1997 are even parity mode, Modbus-RTU is no parity mode.
5. The power data is automatically stored in the memory after power failure and will not be lost for 10 years.
6. After power failure, the battery is used to power the LCD screen to display the power (special customization).
7. Built-in relay remote opening and closing (special customization).
8. Working temperature: -20℃~+55℃
9. Extreme temperature: -25℃~+70℃.
