DDSY315 single-phase four control four metering smart meter (rail type 20A)

Smart meter dedicated MCU and metering chip, with measurement accuracy higher than B (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.

Specifically, there are one in three out, one in four out, and one in five out systems to achieve separate management of lighting, sockets, air conditioning, fans, bathrooms, etc.
