6SE9221-0DC40

The 6SE9221-0DC40 model from Siemens is part of the MICROMASTER series, designated as a versatile drive suitable for various tasks. This equipment handles an input voltage range of 380 to 480 V AC and is rated for an output power of 5.5 kW. With an operating frequency capability of 50/60 Hz at input, it can adjust its output frequency from 0 to 400 Hz. This range provides flexibility in application and control.

The device handles a rated output current of 12 A, which makes it appropriate for many motor control scenarios. It incorporates both V/f Control and Vector Control types, catering to different operational needs. With an overload capacity that can sustain 150% of its rated current for 60 seconds, it demonstrates fine resilience against transient scenarios.

An enclosure rated at IP20 ensures this unit is well-protected from dust and foreign objects, while forced air cooling effectively manages thermal conditions during operation. An LED display simplifies parameter adjustments and improves accessibility, enhancing user interaction with the device. For mounting convenience, this model is wall-mountable.

Additionally, the unit features communication ports including RS-485 and PROFIBUS DP, which facilitate integration into complex network systems. Starting modes include direct-on-line (DOL) and soft start, providing versatile startup options based on application requirements. The drive achieves an exceptional power factor greater than 0.98 and has an overall lightweight design, tipping the scales at just 6.0 kg.
