- When the module is applied, how to operate if 3.3V power supply is required? Answer: if 3.3V power supply is required, the rdj of the module needs to be short circuited (as shown in the figure below). This operation is recommended to be conducted after the test is qualified under 5V power supply, because after short circuiting rdj, the V + V - anti reverse connection function will be invalid, and the module will be burnt directly if connected reversely. 查看详情

- How is the im1281b electric energy metering module connected to the actual load? Does it matter if the fire zero line is connected reversely? Users do not need to worry that the module will be burnt or not measured if the live line and zero line are connected reversely. The module has been processed by hardware design and program to ensure that the positive and negative connection will not affect the use of the module and that the electric energy and electric parameters will be measured correctly. 查看详情

- Can im1281b electric energy metering module communicate with multiple modules through one serial port? If yes, what should I do? Answer: the communication port of im1281b is UART port. This communication port belongs to point-to-point communication. In principle, it is impossible to realize 1-to-many communication. If it is really necessary, one serial port can communicate with multiple modules. It can be realized by adding CD4051 single end 8-channel multi-channel switch core between modules and serial ports. 查看详情

- Can the im1281b electric energy metering module replace the electric energy meter / guide rail meter? Answer: the im1281b electric energy metering module supports MODBUS and DL / T 645-2007 protocols at the same time. Therefore, it can directly replace the electric energy meter for electricity accumulation and electric parameter collection. The user only needs to solve the connection problem of power supply and communication, and does not need to make any changes in the software. Its typical applications include replacing electric energy meters in automobile charging piles. 查看详情

- What is the current range of im1281b electric energy metering module? What if I want to measure a larger current? Answer: the maximum measuring current of im1281b standard is 50A. If AC current or power with larger current range is required, this module can be equipped with AC open transformers (150A, 250A, 500A, etc.) with various ranges. 查看详情
