Control Techniques SK4401

Control Techniques SK4401: Power, Precision, and Proven Performance

The Control Techniques SK4401 is a high-performance inverter drive that delivers exceptional motor control for various industrial applications. As part of the Commander SK series, it is engineered to provide reliable, efficient, and flexible variable frequency drive (VFD) functionality with a user-friendly interface. This model supports three-phase input power (380–480 VAC, 48–62 Hz) and delivers up to 60 amps of output current with an output frequency range of 0–550 Hz, making it an ideal choice for demanding applications that require precision motor speed and torque control. Whether you're operating conveyors, pumps, compressors, or machine tools, the SK4401 is built to meet your performance standards.

Flexible Performance for Demanding Applications

The SK4401 offers 62.3 amps of input and 60 amps of output current, supporting a wide frequency range to accommodate both standard and high-speed motor operation. This extended capability is particularly beneficial in applications requiring precise speed regulation or frequent acceleration and deceleration cycles. The drive's performance characteristics make it versatile across many industries, including materials handling, HVAC, packaging, and general manufacturing. Its powerful vector control algorithms provide strong torque delivery at low speeds and accurate speed holding, even under load variations.

Compact Design and Easy Integration

Despite its power rating, the SK4401 boasts a compact IP20 enclosure, which means it can be mounted inside standard electrical panels without excessive space or additional cooling infrastructure. Designed for ease of installation and commissioning, this inverter drive features simple programming via its integrated keypad and supports multiple control interfaces for flexible integration. Parameter cloning options and onboard diagnostics reduce commissioning time and help maintenance teams quickly identify and resolve issues, minimizing downtime and increasing productivity.

Energy Efficiency Meets Advanced Control

Energy savings are a central focus of the Commander SK series, and the SK4401 continues that tradition by improving motor efficiency and reducing power consumption during partial load conditions. It offers energy-optimizing features that dynamically adjust output to match demand, making it a wise choice for companies aiming to reduce operating costs without sacrificing performance. Its intelligent motor control also minimizes mechanical stress, extending equipment life and reducing service needs.
