1-phase Frequency Converter
- Products for Manufacturers
- 1-phase Frequency Converter
The compact design has a very low noise level as there are no fans in the frequency converter. The frequency converter is thereby maintenance-free, which makes it suitable in many product configurations. Furthermore, all parts are integrated in the product so no external capacitors or inductors are needed. SpeedControl 1145 does not have built-in active cooling.

When the SpeedControl 1145 is to control a compressor motor, it is important that the SpeedControl 1145 is tuned correctly for exactly that motor.
We have already tuned the SpeedControl 1145 to a number of known compressor models and these have each got their own motor profile. The specific motor profile is either selected via ModBus interface or by using a small add-on print which translates ModBus to 0-10V signal. If add-on print is selected, the motor profile selection is easily set via dip switches.
Download motor profiles to get a list of compressor models for which the SpeedControl 1145 is already tuned for.
If you do not find exactly your selected compressor in the motor profile list, we are happy to help tune the SpeedControl 1145 to control your preferred compressor best as possible.
As a rule, new profiles are tuned in our workshop, but in some cases it may be possible to perform the tuning remotely online.
By default, you can choose between cooling plate with horizontal or vertical ribs or cold plate. If you want a different cooling plate, our development department will be happy to assist finding the optimal solution.
