2. What are the characteristics of three-phase energy meters?
I can summarize three features for you:
1. Wide voltage and current operating range. The system has a built-in switch power supply and operates at AC85~285V.. The system adopts a high-precision three-phase electric energy dedicated metering chip, which can measure the active power, reactive power, apparent power, active energy, and reactive energy of each phase and combined phase. It can also measure parameters such as phase voltage, effective current, and power factor. Fully meet the needs of multifunctional energy meters. As long as the system can detect voltage and current, it can measure the electricity used, which is far superior to other three-phase metering products on the market that cannot measure below 200V.
2、 Flexible parameter settings allow users to reasonably set parameters such as time, rate, communication address, baud rate, recharge amount, etc. according to their own needs.
3、 The local LCD and remote control system has a main screen of 128 * 64 and independent buttons added. Users can freely set various parameters on the device. At the same time, the system has an independent monitoring platform, and users can achieve one click operation through the monitoring platform. I hope it can help you!
3. Software for testing positive and negative audio
Currently, there are various audio positive and negative (phase) detection software, including professional audio processing tools, free online tools, and mobile applications, which can meet the needs of different scenarios.
