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

You can view the current positive and negative active and reactive power consumption of the meter, as well as the phase separated electricity consumption of A, B, and C.

• Can support viewing the active power consumption of the past 12 months.

• Total, A, and C power parameters: phase failure, reverse, total reset, and timing event recording functions, as well as phase failure, reverse, and reverse phase sequence alarm prompt functions.

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.

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.
