KD Series Intelligent Frequency Converter

The KD series intelligent frequency converter adopts an advanced dual MCU parallel design architecture. It not only uses current vector control technology that is in line with international leading technology in motor algorithms, but also has rich and powerful functions. Combined with application characteristics, it further strengthens the design of product reliability and environmental adaptability, which can better meet the transmission requirements of various motors. It can rival the world-class variable frequency drive products.
Currently, the KD200 General Purpose Inverter and the KD310 Inverter for the lifting industry have been launched. Among them, the dedicated frequency converters for the lifting industry have multiple control modes, such as V/F control, vector control, etc. It features advanced control functions such as dynamic speed regulation, energy-saving control, and automatic voltage adjustment to enhance the operational efficiency and stability of the motor. It supports multiple communication protocols such as Modbus, Profibus, and CANopen, which can meet the needs of different application scenarios.

KD200 General Purpose Inverter Features

Supports voltage level 380VAC, power level covers 0.75kW～800kW.

Supports V/F control, vector control without PG (SVC) control, vector control with PG (VC) control.

Supports three-phase AC asynchronous motor, three-phase AC permanent magnet synchronous motor.

Flexible command source, frequency source and frequency operation relationship, torque source setting method.

Provides a wide speed regulation range to enable the motor to run at different speeds.

Can provide a variety of additional functions, such as PID control, multi-speed control, DC braking, etc.

Through the smooth acceleration and deceleration control algorithm, mechanical shock and motor operation noise are reduced.

Optimized PID design can make the system run stably and meet the frequent loading and unloading conditions to the maximum extent.

Low-frequency torque is large, and 0.5Hz can output 150% high starting torque.

Support Ethernet, RS485, CANopen and other communication methods.

The entire series uses high-precision Hall effect sensors for output current control, meeting the requirements for rapid control and protection in both hardware and software, and ensuring overall system performance.
