FUTURISE QDM31-1 Three Phase 4 Pole DIN Rail Energy Meter

Main Function

1. Measure the active energy and reactive energy consumption on each phase or three-phase power grid.
2. Measure the instantaneous values, such as voltage, current, active power, reactive power, apparent power, power factor, and frequency.
3. Can do time-of-use metering in 4 tariffs. Can set 8-12 daily intervals. Can freely set the date in every month to read the meter automatically. Can set a single tariff on weekends.
4. Can freely select the block interval demand (default) and sliding-window demand. The demand interval can be set within 1-99 minutes. Automatic resetting of the maximum demand or manual resetting for option.
5. Has a clock chip inside and a maintenance-free lithium battery inside. The battery capacity can be detected in real time and displayed.
6. Can record the electricity data for 12 months. Keeps the data permanently while the power is cut.
7. Display readable without main power (RWP) (optional).
8. Backlights to increase readability in low light conditions (optional).
9. LCD display with two options: cycle display (default) or key display item by item. Can set the cycle display interval. Can select the data item to be displayed.
10. Real-time clock: clock with calendar, timing, and leap year automatic conversion function.
11. LEDs indicate the power supply state, energy impulse signal, load current flow direction, and the data communication state separately.
12. Equipped with RS485 data communication port and (or) IR data communication port for meter setting or reading meter. The meter setting has password protection. The communication protocol complies with standards IEC65056-21, DL/T 645-2007 or MODBUS-RTU, and can also be customized by the user.
13. CT connection three-phase meter, it supports setting the ratio of the external current transformer, and the meter can display the energy value of the primary side for direct viewing.
14. Built-in magnetic holding relay supports load on-off function.
15. Supports multiple remote communication modes, such as Wifi, Bluetooth, LoRa, 2G, 3G,4G.
