SD60 Economic Industrial VFD

SD60 is an economic and compact VFD designed for general-purpose motor control in a wide range of industrial and commercial applications. It supports both V/F and sensorless vector control (SVC), ensuring flexibility and high performance. With features like automatic torque boost, slip compensation, and 150% start-up torque at 0.5Hz, it delivers reliable control under varying load conditions. The SD60 offers high speed accuracy, fast response, and EMC compliance to IEC 61800-3 C3 standards. It supports a wide voltage range (200V–480V), has a coated PCB for harsh environments, built-in RS485 communication, and external keypad support for convenient operation and monitoring.

The key features are listed below:

1. Compact and Economical Mini VFD for General Applications

A new generation of compact, cost-effective VFD designed to control asynchronous AC induction motors in a wide range of industrial and commercial applications.

2. Advanced SVPWM and DSP-Based Control System

Utilizes space vector pulse width modulation (SVPWM) and a high-speed DSP controller to enhance control precision, stability, and overall system reliability.

3. Dual Control Modes: V/F and SVC

Supports both V/F control and sensorless vector control (SVC), offering flexible control strategies tailored to different load types and dynamic performance needs.

4. Automatic Torque Boost and Slip Compensation

Automatically adjusts torque and compensates for motor slip to maintain consistent output, especially under fluctuating loads or during acceleration.

5. Rapid Acceleration and Deceleration Response

Delivers smooth and responsive motor control during fast start and stop operations, minimizing mechanical stress and downtime.

6. 150% Start-Up Torque at 0.5Hz

Capable of providing 150% rated torque at 0.5Hz, making it ideal for heavy-load startup conditions and low-speed torque-demanding processes.

7. High Speed Accuracy Across Full Range

Ensures stable speed control with less than 0.5% deviation, delivering smooth performance across the entire speed range without vibration or overshoot.

8. EMC Compliance to IEC 61800-3 C3 Standard

Excellent anti-electromagnetic interference capabilities meet international EMC requirements, ensuring stable operation in electrically noisy environments.

9. Wide Input Voltage Range: 200V to 480V

Supports a broad voltage range, allowing the VFD to operate reliably in areas with unstable power supply or varying voltage conditions.

10. Coated PCB for Harsh Environment Protection

The control board is thickened and treated with anti-moisture coating, providing resistance to high temperature, high humidity, dust, and other harsh environments.

11. Built-In RS485 Communication Interface

Equipped with integrated RS485 port for seamless communication using Modbus RTU protocol, enabling easy integration into automation systems.

12. External Keypad Support for Easy Operation

Allows for connection of an external keypad, providing convenient access for parameter setting, real-time monitoring, and fault diagnosis.
