This product is an industrial-grade dual-channel high-power detection circuit board, integrating two complete sets of high-precision electrical energy metering systems. It adopts industrial-specific metering chips, enabling simultaneous and accurate measurement of all electrical parameters of two independent circuits or different power supply lines of the same equipment. Data is reliably transmitted via a 485 communication interface, and a full-range isolation protection design ensures stable operation in complex industrial electromagnetic environments. It meets the requirements of industrial sites for energy efficiency monitoring, fault diagnosis and quality control of high-power equipment.
