Technical Specifications & Selection Guide

Selection Tip: The SKC3400220 is the standard 2.2kW 400V-class variant of the Commander SK range. For 200V-class or higher power ratings, consult our team for alternative Commander SK models.

Core Features & Technical Advantages

• Robust Open-Loop Vector Control — Delivers precise torque and speed regulation without encoder feedback, reducing system complexity while maintaining heavy-duty performance across variable load profiles.
• Wide Input Voltage Tolerance (342-528VAC) — Engineered to withstand real-world supply fluctuations common in industrial facilities, protecting connected motors from voltage-induced stress.
• Configurable Switching Frequency (3-16kHz) — Allows engineers to balance acoustic noise reduction against thermal performance, critical in noise-sensitive or thermally constrained enclosures.
• Integrated Modbus RTU / RS-485 — Native fieldbus support enables direct integration into PLC System and DCS architectures without additional gateway hardware.
• Dynamic Braking Ready — Optional braking resistor support enables rapid, controlled deceleration in high-inertia applications such as centrifuges and hoists.
• Compact Wall-Mount Form Factor — The precision-engineered 260-115-175mm chassis maximizes panel space efficiency in retrofit and greenfield installations alike.
• Comprehensive Protection Suite — Overcurrent, overvoltage, undervoltage, phase loss, and motor thermal protection are all integrated, minimizing unplanned downtime.

Typical Application Scenarios

Oil & Gas — Pipeline Pump Control: Upstream and midstream operators rely on the Commander SK series to regulate centrifugal pump speeds in crude transfer and water injection systems. The SKC3400220’s robust overload capacity (150% for 60 seconds) handles the demanding start-up torque profiles typical of pipeline pump stations without tripping.

Power Plants — Cooling Tower Fan Drives: Thermal power stations deploy this drive to modulate cooling tower fan speeds in response to condenser temperature feedback. Variable speed operation reduces fan motor energy consumption by up to 50% compared to fixed-speed damper control — a measurable contribution to plant efficiency KPIs.

Water & Wastewater Treatment — Aeration Blowers: Municipal and industrial water treatment facilities use the SKC3400220 to control aeration blower output, maintaining dissolved oxygen setpoints while minimizing energy expenditure during low-demand periods.

Food & Beverage — Mixer and Conveyor Lines: Hygienic production environments benefit from the drive’s smooth acceleration ramps and precise speed control, preventing product spillage on conveyors and ensuring consistent mixing ratios in batch processing tanks.

Pharmaceutical Manufacturing — HVAC and Clean Room Ventilation: Controlled environments demand stable, low-noise airflow management. The configurable switching frequency of the SKC3400220 allows acoustic optimization, while Modbus integration supports BMS (Building Management System) connectivity for centralized monitoring.
