Product Description
SpeedControl 1047 is a frequency converter for control of 3-phase EC, PMSM and BLDC motors up to
1500W/5.5A with single phase supply. SpeedControl 1047 is delivered enclosed in an IP 54 metal housing for
demanding environments or without enclosure for build-in constructions. The compact construction offers
many mounting options. The construction is not equipped with active cooling, the sound level is very low,
and the frequency converter is maintenance free.

Considerations for Compressor use
For each compressor, the compressor data from the manufacturer datasheet must be hard wired into the
frequency converter software by LS Control. Afterwards the specific compressor is selected by means of dip
switches. Since the compressor parameters change with changing loads, LS Control must carry out a
performance test on each individual compressor to select the best parameters covering the widest range of
operating patterns ensuring that the compressor will be able to operate at high loads as well as low loads.
The result of the performance test will give a new max. current and new max. RPM for correct operation of
the compressor in question.
Rule of thumb! When using a compressor with a frequency converter, make sure that the input power to
the compressor is below the maximum power of the frequency converter and that the frequency converter
can deliver the required current for the compressor.
Application considerations with compressors
To choose the right compressor for your specific application, it is important to compare the compressor
data with the frequency converter data. Make sure that both the frequency converter and the compressor
can supply the required power and current for your application.
At high loads the frequency converter may become extremely warm. Therefore, if the compressor is
operated at high loads and high ambient temperatures, active cooling might be necessary. Please refer to
chapter Electrical / Mechanical installation.
NB! It is your responsibility to ensure that the installation in all meets the EMC standards applying for your
specific installation and the environment in which it is installed.
