Product Description
SpeedControl E 1045 is a frequency converter for control of EC, PMSM, BLDC and standard asynchronous
motors up to 1500W/5.5A or 2000W/6.5A for 3 phase motors with single phase supply. SpeedControl E
1045 is enclosed in an IP 54 metal housing for demanding environments. 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.
• Descrete light grey color for reduction of heat absorption.
• Silent and reliable with an advanced self protection feature.
• Provided with a user-friendly interface for quick and easy installation.
• Designed for use in many different applications, including pump, ventilator and compressor
applications. Depending on motor profile.
• For special applications, please contact us for further information.
Considerations if used with compressors
For each compressor, the compressor data from the manufacturer datasheet are hard wired into the
frequency converter software by LS Control. The specific compressor is selected by means of dip switches.
Since the compressor parameters change with changing loads, LS Control must carry out a perform 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 be 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 as a whole meets the EMC standards applying for
your specific installation and the environment in which it is installed.
