The SINAMICS G120P is a cost-effective, energy-efficient and easy-to-operate inverter with a wealth of functions. As a result of the integrated, application-specific and energy-saving functions, the inverter facilitates cost-effective and efficient operation. It is tailored to address pump, fan and compressor drives in the public domain as well as the industrial environment. Furthermore it sets itself apart as a result of its simple installation and commissioning. It is used for basic speed control as well as for complex closed-loop control tasks in building technology as well as the water and process industries. SINAMICS G120P is available as a built-in device up to 630 kW (700 hp) in an IP20 degree of protection, as well as for wall-mounting up to 90 kW (125 hp) in an IP55 degree of protection.

SINAMICS G120P is a modular inverter system, comprising the closed-loop control unit (Control Unit), a power unit (Power Module) as well as an operating unit. The latter is either the Intelligent Operator Panel or the Basic Operator Panel.

• The Control Unit controls and monitors the Power Module and the connected motors in several selectable operating modes. It supports communication to a local control system as well as to monitoring equipment.
• The Power Module supplies the motors in a power range from 0.37 kW up to 630 kW (0.5 hp – 700 hp)
• The IOP and BOP-2 operating units optimally support users when it comes to operation and commissioning
