The MICROMASTER 440 series 6SE6440-2AD32-2DA1 serves as an effective frequency converter with notable specifications. It operates at a rated power output of 22 kW and accepts a 3-phase AC input voltage within the range of 380 to 480 volts, accommodating fluctuations under the +/-10% guideline. The input frequency spans from 47 to 63 Hz, allowing compatibility with standard supply sources.
This unit offers a flexible output frequency that extends from 0 to 500 Hz, facilitating applications that require variable speed control. The constant torque mode enhances performance, particularly in scenarios with consistent load demands. Additionally, the converter features an overload capacity of 150%, enabling it to handle surges for up to 60 seconds without damage. It exhibits square-law torque characteristics with an output capacity of 30 kW, thereby further enhancing its operational versatility.
Designed with an IP20 degree of protection, the converter is suitable for less demanding environments. Meanwhile, its operational temperature range spans from -10°C to +50°C, making it adaptable to various conditions. The built-in Class A EMC filter minimizes electrical interference, which is critical in sensitive installations. Notably, this version does not include an Operator Panel (AOP) or Basic Operator Panel (BOP) with its display, streamlining its design.
For control circuitry, a 24 V DC control voltage is utilized, enabling reliable operation in tandem with various control systems. Lastly, the overall dimensions of this unit measure 520 mm in height, 275 mm in width, and 245 mm in depth, promoting compact installation capabilities in tight spaces.
