Product Overview
The Siemens 6SE6440-2AD31-1CA1 is a high-performance vector-controlled frequency inverter from the MICROMASTER 440 series, engineered for sophisticated industrial motor regulation. This 11kW (Constant Torque) powerhouse provides precise speed and torque control for three-phase AC motors, featuring an integrated Class A EMC filter to mitigate electromagnetic interference. Designed for versatility, the unit supports both heavy-duty applications requiring high starting torque and centrifugal loads like fans and pumps. While currently a legacy component, its robust electrical design and advanced control algorithms continue to make it a critical asset for maintaining existing automation infrastructure and specialized process machinery.
Core Engineering Specifications and Performance Data
This AC drive is characterized by its high overload capacity and adaptable power stage, suitable for global industrial electrical standards:
-
Power Ratings: Delivers 11 kW (15 HP) for constant torque loads and up to 15 kW for variable torque applications.
-
Input Parameters: Supports a 3-phase supply of 380V to 480V AC (±10%) at a frequency range of 47 to 63 Hz.
-
Overload Resilience: Engineered for high-stress starts, offering 150% rated current for 60 seconds and a 200% peak surge for 3 seconds.
-
Control Architecture: Features sophisticated vector control for superior dynamic response and torque stability even at low speeds.
-
Integrated Filtration: Built-in Class A Filter ensures compliance with industrial electromagnetic compatibility standards without external hardware.
-
Thermal Range: Fully operational in ambient temperatures from -10°C to +50°C, optimized for unheated industrial enclosures.
-
Modular Interface: Requires an external operator panel (BOP or AOP) or a communication module (Profibus/DeviceNet) for parameterization and control.
-
Physical Housing: Compact Frame Size C (FSC) with an IP20 protection rating, measuring 245 x 185 x 195 mm.
