Information About SKC3400400
The Control Techniques SKC3400400 is a high-performance AC motor drive engineered for demanding industrial environments. As part of the Commander SK series (also known under the DigiDrive SK family), this model combines simplicity, flexibility, and performance in a compact IP20-rated chassis.
This 4 kW, 9 A inverter supports both V/f and open-loop vector control, enabling precise speed or torque regulation for a wide range of applications. With intuitive setup menus, built-in I/O, and Modbus RTU communications, the unit delivers more functionality than a typical open-loop AC drive. Users can access advanced features such as PID control, logic functions, threshold detectors, DC injection braking, dynamic braking transistor, and energy-optimized motor flux control.
The drive features onboard intelligence that allows programming through standard parameter menus or enhanced logic blocks when paired with optional modules such as LogicStick or I/O expansion solutions. For applications requiring extended communication capability or fieldbus integration, optional modules—including Ethernet, Profibus, DeviceNet, and more—can be added quickly.
Designed for reliability, the SKC3400400 offers 150% overload capability for heavy-duty operation and includes features like automatic no-spin autotune, multiple preset speeds, selectable acceleration profiles, and a wide output frequency range up to 550 Hz (standard) or 1500 Hz using advanced modes. These capabilities make it suitable for conveyors, pumps, fans, machine automation, and general industrial motion control.
Built with Control Techniques’ high-quality engineering and global certification (CE, UL), the SKC3400400 provides stable and efficient performance while offering long-term reliability backed by industry-leading support.
Key Features
- 4 kW / 9 A output for 380–480 VAC 3-phase motors
- Simple setup and commissioning via intuitive parameter menus
- Open-loop vector & V/f control for speed or torque-based applications
- Modbus RTU (RS485) communication via RJ45
- Dynamic braking transistor built-in
- DC injection braking
- Automatic no-spin autotune
- 8 preset speeds
- Advanced software functions: timers, thresholds, math blocks, logic operators, PID controller, kWh meter
- High switching frequency (3–18 kHz) for quiet motor operation
- Output frequency up to 550 Hz (standard) / up to 1500 Hz (advanced)
- Energy-saving motor flux optimization
