discuss personally
| Brand | Wone |
| Series | DEM2D102 |
Description
The DIN RAIL DC meter's surface panel is designed with two buttons, through which you can query power data and set parameters. There is a lead seal design on the cover plate of the power terminal cover which protects the wiring and prevents the user from changing the wiring and anti-tamper.
Features
RS485 communication: used for parameter setting, data reading; DTL645 protocol/Modbus Protocol.
DC metering: using shunt sampling, high measurement accuracy; can measure DC power, current, voltage.
Alarm function: Over-current alarm: When the current exceeds the CT1 value set by the meter, an alarm event occurs, and the alarm light on the electrical surface panel lights up (yellow light).
At the same time, the value of the corresponding alarm status register will change, and the user can read this register through communication to determine whether an over-current alarm has occurred.
Display: LCD with backlight ,Support Various parameters display,energy data and Instantaneous parameters.
Firmware upgrade: RS485 local upgrade.
