Product Details

Sysolution Electric Energy Statistics Senor RM1275

Product Introduction:

RM1275 single-phase AC energy metering module is a new product released by Sysolution Technology to accommodate various manufacturers to monitor the power consumption of their products. The software and hardware platform it uses has been applied in a large number of industrial products such as smart meters, and is the smallest unit to achieve power metering.

Applications:

RM1275 has been applied on a large scale in many industries, such as AC charging pile, street lamp post monitoring, machine room, base station monitoring, energy-saving transformation, intelligent power management, dynamic loop, security monitoring, equipment energy consumption monitoring, etc. The accuracy of the module is better than the national level 1 standard; it can measure AC voltage, current, power, power factor, frequency and other electrical data from 45 to 65Hz; its communication protocol conforms to Modbus RTU communication protocol and DL/T645-2007 multi-functional energy meter communication, and it is easy to connect with other micro controllers and ARM to realize automatic data acquisition and monitoring through corresponding interfaces.

This module can be easily embedded in street lamp post monitoring, smart home, smart household appliances, energy-saving transformation, intelligent power management, security monitoring, equipment energy consumption monitoring and many other industries, is an important supporting module to follow the trend of Internet of Things.

Functions & Features:

Single module can achieve the collection of single-phase AC parameters, including voltage, current, power, power factor, frequency, electrical energy, temperature multiple electrical parameters, which provide overall information.
Adopt industrial-grade special power metering SOC chip, with high measurement accuracy.
Standard 485 communication, communication port with ESD protection, communication protocol supports DL/T 645-2007 and MODBUS-RTU dual statute.
Flip over and restart the measurement after the electricity is fully stored, and the electricity data is protected by power down.
Adopt current transformer with aperture Φ12.8mm, user can use Cable lug, which is convenient for user.
When the load uses electricity, the PF pin will output the corresponding pulse. This pin can also be used for the calibration bench to check the power measurement accuracy of the metering module through pulse acquisition.
