Functional classification

• Energy metering function: Single phase active energy metering function, the reverse electricity is included in the total forward electricity, and the forward and reverse are accumulated separately. The combined active total energy is the forward electricity plus the reverse electricity.

• Display and storage functions: equipped with rich status indicators and Chinese character prompts, with backlight; Using LCD to display the electricity data of the past 3 months

• Storage function: It can store monthly electricity data from January to December, as well as total, peak, average, and valley electricity data for each month

Data output and communication function: Meter reading/far-infrared can be done through RS485 communication port, and with the meter reading system, various electricity data of the meter can be read. Supports DL/T645-2007 multifunctional energy meter communication protocol.

Carrier communication function: supports remote power on/off function.

Anti theft function

If a user illegally removes or cuts off voltage or current connections, the electricity meter will issue an alarm signal until the user resumes normal electricity use.

• Open lid recording function

Prevent illegal changes to the circuit.

Lead sealed anti-theft function

Lead seals cannot be restored after one-time use.

Conventional display content of LCD screen

• It can display the current positive active peak, peak, flat, and valley electricity levels

You can view the electricity consumption in the previous three months

Meter reading method

• Display meter reading: By pressing the buttons on the meter, the monthly total electricity, voltage, current, power factor, and other data of the meter can be queried on the LCD screen.

Power outage meter reading: Equipped with a power outage meter reading battery to provide the energy required for the operation of the energy meter, in order to maintain the relevant data in the meter.

Communication meter reading: Through RS485 communication port meter reading and handheld infrared meter reading machine, combined with meter reading system, various electricity data of the meter can be read. And supports DL/T645-1997 multifunctional energy meter communication protocol.
