6SL3210-1KE21-7UP0

The Siemens 6SL3210-1KE21-7UP0 compact inverter from the SINAMICS G120 series is engineered for versatility in various applications. Capable of handling a motor power output of 7.5 kW (10 HP), it facilitates effective control for different motor types. Designed for 3-phase input power, the inverter operates within a nominal voltage range of 380 to 480 VAC, ensuring compatibility with standard systems.

The unit exhibits a continuous current capacity of 16.5 A under low overload conditions and 12.5 A under high overload conditions, providing flexibility for diverse demands. The inverter's mechanical size is classified as FSB, optimizing its installation requirements.

For power supply, it accommodates frequencies between 47 and 63 Hz. Users can benefit from the frequency output configuration, which enables variables from 0 to 550 Hz when employing V/F control mode. Alternatively, in vector control mode, the frequency output is from 0 to 240 Hz, offering precision during operation. Pulse width modulation operates at a nominal frequency of 4 kHz and supports a maximum of 16 kHz for optimal motor response.

The unit utilizes internal air cooling to maintain operational efficiency and can operate up to an altitude of 1000 meters (3281 feet). It also features a short circuit interrupting capacity of 100 kA, ensuring robust protection in the event of fault conditions. With an IP20 protection class, the inverter is designed for environments that require protection against solid objects larger than 12.5 mm.
