DDZY315-G single-phase cost control smart meter (rail mounted 4G/NB-IOT)

Smart meter dedicated MCU and metering chip, with metering accuracy higher than 1.0 level.

● LCD large screen displays total power consumption, remaining power.

● Optoelectronic isolation RS485 communication interface, lightning protection, surge protection, and interference prevention.

Automatic power outage for overdue payments, automatic incoming calls for recharging, and reminders for minimum balance.

● Safety management functions such as remote manual power on/off, timed automatic power on/off, overload tripping, time limited current, temperature detection, infrared remote control, etc.

Built in hardware clock circuit, with local data storage, supports remote precise timing and rate setting.

Measure and record electrical parameters such as voltage, current, power, and power factor.

● Record events such as zeroing, timing, remote tripping, and remote closing.

Independent embedded software ensures normal operation when disconnected from the internet, realizing metering deduction and policy control, strict password verification and security authentication, and secure and reliable data transmission.

Built in 4G/NB-IOT/WIFI IoT wireless module, does not require a gateway to directly connect to the background, and can customize dual control and dual metering functions.

The dual circuit rail smart meter can independently measure and strategically control the two circuits of dormitory air conditioning and lighting sockets.
