AC80B medium voltage VFD drive is developed on the basis of advanced platform of AC80 that it has stable and high working performance. Below are its main features:
a. It is developed for the second time on the mature platform of AC80.
b. Designed with optimized structure that its stability and service life has been greatly improved.
c. In order to optimize the inner structure of control cabinet, all the models above 93KW adopts upper-input and bottom-output wiring method.
d. All the models above 30KW are all built-in with DC reactor in order to reduce the input harmonic, improve input power factor and protect your grid. All the series have been reserved with DC reactor connection terminal.
a. All the standard products are painted with three-proofing lacquer which is imported from Germany. For the occasions of excessive humidity or dust, we provide special protection or treatment measures for the sake of meeting long-term stable running requirements in harsh environment.
b. It adopts air duct isolation technique which ensures it can work in severe industrial application environment.
c. For special applications, we can provide it to customers with sealed design.
a. It adopts international standard ModBus communication protocol. Users can set control command, running frequency, related parameters, status and more actions via PC, PLC, and master frequency converter to achieve centralized control, for meeting application requirements perfectly.
b. AC80B series support bus expansion, through options, it can even support the Profibus protocol.
a. It supports wide working voltage range. When the voltage is low, it can guarantee the load capacity through modulation technique.
b. It meets industrial standards in power surge, power grid noise and static reactive immunity.
c. The control power and bus power has been separated. Control power adopts separate power supply via isolation transformer, and standard-designed filter circuit.
