Overview
The Siemens 6SE6420-2UC12-5AA1 is a compact unfiltered AC drive in the Micromaster 420 series. This inverter drive is engineered for general-purpose variable-frequency motor control in industrial automation, process control, and motion applications. Its single-phase or three-phase 200–240 V input capability makes it versatile for both OEM and retrofit installations where space and electrical infrastructure are constraints.
Key Features
- Compact Form Factor: Dimensions of 173 × 73 × 149 mm (H × W × D) fit tight panel spaces and DIN rail mounting.
- Wide Output Frequency Range: 0–650 Hz output supports a broad range of motor speeds and load profiles.
- Robust Overload Rating: Constant-torque rating of 0.25 kW with 150% overload capacity for 60 seconds, ideal for demanding applications.
- IP20 Protection: Standard industrial enclosure rating provides protection against ingress of dust and indirect water spray.
- Optional Communication: Supports PROFIBUS, AS-Interface, and DeviceNet modules for networked control.
