Already known from the Siemens SCE program, the SINAMICS G120 frequency inverter is now also available as a learning board.
Whether you are doing exercises for pumping, ventilating, compressing, moving or processing: SINAMICS G120 is the universal drive for the most diverse requirements.
All connections are led out to the front panel with 4mm safety lab jacks. A motor can be connected either via the laboratory sockets or the parallel available connection socket. The extensive protective functions protect the drive and the connected motor.
Power supply 1-phase 230 V AC, output 3-phase 230 V for motors with up to 0.75 kW rated power.
Siemens provides the "starter" commissioning software free of charge for commissioning and parameterization. It can be downloaded from the Siemens website, as well as the manuals for the inverter.
The learning board is equipped with a SINAMICS Power Module PM240-2:
- Power factor 0.85
- Displacement angle cos phi 0,95
- Efficiency 0,96
- Power supply 1-phase 200-240 V AC, 47-63 Hz
