The IM1253C single-phase AC and DC energy metering module is developed by Shenzhen iRdopto Optoelectronics Co., Ltd. 

in order to adapt to various manufacturers to monitor the power consumption of their products.It is also a supporting module for 

manufacturers of various power monitoring needs in many industries such as charging piles, street lamp monitoring, computer room, 

base station monitoring, energy-saving renovation, intelligent power management, Field Supervision Unit, security monitoring, 

equipment energy consumption monitoring and many other industries.The accuracy of the module is better than the national level 1 

standard; it adopts industrial-grade special energy metering SOC IC; it is convenient to connect with other single-chip microcomputers 

through the corresponding interface to realize automatic data acquisition and monitoring functions

The IM1253C single-phase AC/DC energy metering module is also a module in our IM metering module series that can communicate 

with 485 and can measure DC. Compared with the UART port that can only communicate one-to-one, 485 communication perfectly 

solves the problem that customers want to use multiple modules at the same time. At the same time, it also saves the serial port resources 

of the MCU to a great extent, and one MCU can manage up to 256 modules. And the RS-485 interface is a combination of a balanced driver 

and a differential receiver, and the anti-common mode interference ability is enhanced, that is, the anti-noise interference is good.

At present, the company's IM series AC and DC metering modules have been widely used in AC and DC charging piles, smart homes, Field

 Supervision Unit( FSU), smart security, lighting monitoring, smart parks, digital computer rooms, energy management, battery monitoring 

and other fields, and have been adopted and recognized by benchmarking companies in various industries.

This module can be easily embedded in many industries such as street lamp monitoring, smart home, smart home appliances, energy-saving 

renovation, smart power management, security monitoring, equipment energy consumption monitoring, etc. It is an important supporting module 

for the Internet of Things era.
