Variable Frequency Drive | Siemens | 6SE6420-2UD23-0BA1 3KW 380V 6SE6 420-2UD23-0BA1

Product Description: 6SE6420-2UD23-0BA1

The 6SE6420-2UD23-0BA1 is a MICROMASTER 420 series VFD designed for precise speed and torque control of three-phase AC motors up to 4 kW (5 HP). It accepts a 380–480 V AC ±10 % input, features sensor-less vector control, and includes an integrated braking chopper. Delivered without an internal EMC filter, it allows users to install a site-specific external filter. Enclosed in an IP20 panel-mount housing, it’s ideal for pumps, fans, conveyors, and general-purpose machinery.

Key Features

• Sensor-less Vector Control: High dynamic response and accurate speed regulation
• Integrated Braking Chopper: Supports rapid deceleration with an external resistor
• Flexible I/O: 3 programmable digital inputs; 1 analog input (0–10 V / 0–20 mA); 1 analog output; 1 relay output
• Modular Communications: Optional PROFIBUS-DP, CANopen, DeviceNet, or USS (RS-485) modules
• Quick Commissioning: Parameter macros and Basic Operator Panel (BOP) or PC STARTER tool
• Wide Temperature Range: –10 °C to +50 °C (up to +60 °C with derating)
