Siemens 6SE3212-7DA40 Micromaster Vector AC Drive

Siemens 6SE3212-7DA40 Micromaster Vector AC Drive is a compact 1.1 kW variable-speed inverter (MMV110/3) designed to drive 3-phase motors from a 380–500 V AC supply, with unfiltered input and a voltage tolerance of ±10% at 50/60 Hz. As a member of the MICROMASTER Vector family, it uses vector control to deliver smooth torque and precise speed across the motor’s range. It is rated for continuous 1.1 kW output with overload capability of 150% for 60 seconds and 200% for 3 seconds to handle brief peak loads. The drive’s enclosure measures 175 × 73 × 141 mm (H × W × D) and weighs 0.85 kg, with IP20 protection and an operating ambient temperature range of 0–50°C, making it appropriate for compact control panels in industrial environments that require reliable motor control from a small footprint. It is suitable for general purpose motor control in automation applications. With a 380–500 V input, it aligns with common European power distributions.
