Features:
- Provides high starting torque and handles temporary load spikes without tripping; ideal for pumps, fans, and conveyors.
- Accepts industrial three-phase mains globally; 1.1 kW (1.5 hp) output for small to medium motor control.
- Small footprint, IP20 protection, lightweight (1.00 kg); includes 3 DI, 1 DO, 1 AI, 1 AO for basic I/O.
The 6SE6420-2UD21-1AA1 is designed to handle temporary high torque demands without interrupting operation. Its high overload (HO) rating allows the drive to deliver 150% of its rated output current (3.00 A × 150% = 4.50 A) for 60 seconds, followed by 100% output for 240 seconds within a 300-second cycle. This capability is critical for applications where the motor experiences intermittent peak loads.
The 6SE6420-2UD21-1AA1 is a three-phase input drive designed for global industrial mains. It accepts 380-480V AC ±10% at 47-63 Hz, covering the standard voltage ranges found in Europe (400V), the UK (415V), and many Asian countries (380V, 440V). This wide tolerance means the drive will operate reliably even when the mains voltage fluctuates due to grid conditions or large nearby loads switching on and off. The rated input current at high overload (HO) is 4.90 A. The drive’s output is three-phase AC at up to 480V, with a rated output current of 3.00 A at 1.10 kW (1.50 hp).
The 6SE6420-2UD21-1AA1 is a size FSA drive – the smallest frame size in the MICROMASTER 420 family. Its compact dimensions (73 mm wide, 173 mm high, 149 mm deep) and low weight (1.00 kg) make it easy to mount in crowded control cabinets. The IP20 protection rating means the drive is suitable for installation inside an enclosure, protecting it from dust and accidental contact. The narrow width (73 mm) is particularly valuable when multiple drives must be placed side by side. The drive’s terminals are accessible from the front, simplifying wiring. Mounting is typically on a DIN rail or directly onto a backplate.
The 6SE6420-2UD21-1AA1 Siemens Inverter may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL)by the manufacturer (OEM).
