Is there any restriction on the installation direction when installing a frequency converter.

It should be basically stored in the tray, but the problem is that the tray with a fully enclosed structure has a large external size, occupies a large space, and has a relatively high cost. The measures include:

(1) The design of the disk should be tailored to the heat dissipation required by the actual device;

(2) Using aluminum heat sinks, wing cooling agents, etc. to increase the cooling area;

(3) Use heat pipes.

Why can't a frequency converter be used as a frequency converter power supply?

The entire circuit of a variable frequency power supply consists of AC DC, AC, and filtering parts, so the voltage and current waveforms it outputs are pure sine waves, which are very close to an ideal AC power supply. It can output the grid voltage and frequency of any country in the world. And the frequency converter is composed of circuits such as AC straight current and AC (modulated wave), and the standard name for the frequency converter should be frequency converter speed controller. The waveform of its output voltage is a pulse square wave with many harmonic components. The voltage and frequency change proportionally at the same time and cannot be adjusted separately, which does not meet the requirements of AC power supply. In principle, it cannot be used as a power supply and is generally only used for speed regulation of three-phase asynchronous motors.
