Audited Supplier AC10 series frequency inverter is a product developed on the latest technology platform of VEICHI. AC10 products are based on the user's market demand for miniaturization, high reliability and high cost performance. As a narrow-body VFD, AC10 has convenient way of installation, small size, low temperature rise, high protection, strong software performance and many other advantages. AC10 development relies on advanced PLM R&D management system to ensure that the hardware, software, structure and test process are three-dimensional, systematic and can be developed during the development process. Traceability, constant scrutiny in every detail ensures strict rigor and scientific spirit (T3 VFDs only support vector control).
Independent air duct design, fast heat dissipation, the low-temperature rise of the machine, no need to derating in a high-temperature environment.
>>> Structural design high protection
Through real-time monitoring of the load current during operation, it is automatically limited to not exceed the set overcurrent suppression point, which has prevented the fault trip caused by the current. This function is especially suitable for some loads with large inertia or severe changes.
>>> Overvoltage suppression protection
When the bus voltage reaches or exceeds the bus overvoltage suppression point during the operation of the inverter, the inverter will automatically adjust the operating frequency to suppress the excessive bus voltage, to ensure that the inverter does not cause overvoltage protection due to the excessive bus voltage.
When the output current exceeds the wave-by-wave current limit point, the hardware current limit protection is triggered, which can restrain the rise of current to a certain extent so that the current does not exceed the inverter protection value, and avoid the current alarm and shutdown due to sudden load or abnormal current.
The computer can manage the parameter storage and download of several inverters. The parameter download function can save the parameter setting work when exchanging the inverter. The monitoring software is equipped with various monitoring, parameter settings, motor self-learning, oscilloscope functions, etc. Only need a simple RS485 serial port, you can simply connect to the computer.
Application: fan and pump, automated production line, carpentry machinery, smart logistics, food packaging line, and other industries and equipment.
