Product Description

3phase Medium Voltage VFD Frequency Converter


ZK SD300 series medium voltage frequency converter mainly features:


ZK SD3000 series Medium Voltage Drive is high-high voltage device, which is controlled by DSP, with the SVPWM and cell in series multi-level technology to guarantee the inverter to suit industrial fields. The harmonic content is much smaller than the standard of IEE519-1992. It has high power factor and good output wave quality without input filters, power factor compensation device and output filter. Motor heating caused by harmonics and Torque ripple, noise, dv/dt, and common mode voltage problems are also avoided. It fits for asynchronous and synchronous motors.


Three-level drive technology, lower output harmonics, waveform closer to sine wave, lower motor heating, longer motor workinglife

High performance for driving permanent magnet synchronous motor and AC asynchronous motor

Compatible with 6 pulse, 12 pulse, 18 pulse, 24 pulse, multiple voltage input modes, allowing grid voltage range from 85% to 115%

V/f control and high-performance vector control can be provided to achieve two-quadrant and four-quadrant operation, saving energy and reducing consumption;

The larger starting torque to easy move the load, soft start and soft stop to eliminate the mechanical and electrical impact, to extend the service life of the equipment; 150% starting torque is available when 1Hz reaching.

With CAN, Rs485 and other communication interfaces, it can realize communication with the host computer, realize the centralized control operation of multiple devices, and transfer the operation data to the ground dispatching room for remote supervision.

Multi-channel digital, analog I/O interface

Compatible with European control mode; capable of master-slave control of multi-machine dragging device

Power balance during runing (no need to install encoder) and synchronous speed driving

It has perfect protection functions such as overcurrent, overload, short circuit, phase loss, leakage lockout, overvoltage, undervoltage, overheating and other protection functions.
