Introduction
This meter is designed and manufactured with stable performance, low power consumption industrial-grade components and SMT technology. It is suitable for users who implement single-rate electricity prices, such as small and medium-sized enterprises, commercial users and residential users, as well as three-phase electrical equipment. It can be networked via RS485 communication. Product standard: GB/T17215.321.
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).
