ST300 400V Frequency inverter 0.75kW to 7.5kW

The compact ST300 series frequency inverter impresses with its design and is ideal for installation in switchgear. The possibility of side-by-side installation means that the usually limited space in switch cabinets can be utilised as effectively as possible. As the power is fed in from above, installation in large systems is particularly efficient. Alternatively, frequency inverters with a rated output of up to 4 kW can be mounted on a DIN 35 mounting rail using an adapter plate. The control cable is connected via terminals with push-in technology and is therefore particularly uncomplicated, quick and safe. Shield support plates at the top and bottom are available for EMC-compliant installation. Every frequency inverter in the ST300 series has the STO safety function (SIL3, PLe). The frequency inverter is suitable for TT, TN and IT systems. Parameterisation of the frequency inverter is extremely simple thanks to the carefully compiled German operating instructions. Sourcetronic also has an extensive range of frequency inverter accessories such as EMC filters, mains chokes and braking resistors.

Areas of application for the 400V frequency inverter

A frequency inverter is always necessary if a drive is to be operated with a variable frequency. Large industrial machines, pump systems or compressors are just some of the applications for which a frequency inverter is the right choice.
