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℃.
