Low frequency inverter is a kind of power product working in high current and high frequency environment, and its potential failure rate is quite high. Therefore, consumers must be careful when buying:
First, select from
the low frequency inverter output waveform, preferably not lower than the quasi sine wave;
Secondly,
the low frequency inverter should have complete circuit protection function;
Third, manufacturers should have good after-sales service commitments;
Fourth, circuits and products have been tested for a period of time.
