Siemens Micromaster 411 /Combimaster 411 AC Drives

Siemens Series frequency converters Micromaster 411 designed to work with asynchronous motors with a power of up to 3 kW in harsh conditions requiring reliable protection from ingress of water and industrial dust. They can be used in a wide variety of applications, are most in demand as part of the drives of pumping and ventilation equipment, conveyor installations.

The modular construction concept allows you to select the optimal operating parameters and optional blocks. Effective natural cooling (convection) due to a special design, isolation of electronic components and junction box, extensive braking system capabilities. Version of execution Combimaster 411 It is supplied complete with a motor.
