Product Description
Siemens Micromaster 440 model 6SE6440-2UD15-5AA1 is a compact variable frequency drive engineered for demanding constant‑torque applications. Rated at 0.55 kW (0.75 HP), it operates on 3‑phase 380–480 VAC input with a 47–63 Hz supply range and delivers up to 550–650 Hz output frequency depending on control mode. Frame size FSA with IP20 protection provides a small footprint for cabinet installations, and the unit runs without an integrated line filter. The drive supports robust motor protection with undervoltage, overvoltage, overload, stall, short‑circuit, and thermal safeguards, and offers high overload handling typical of the MM440 series. Integrated RS‑485 communications and multiple configurable digital and analog I/O simplify control integration. Typical dimensions are approximately 173 x 73 x 149 mm and current rating around 1.7 A, suited for small motors in conveyors, pumps, and packaging equipment. The drive is optimized for standalone operation and can be commissioned without an AOP/BOP if desired. Package typically includes the base drive; external filters, operator panels, and braking options are available separately.
