Technical FAQs 4

What is a frequency inverter?

A frequency inverter also called frequency converter, is a power control conversion device to convert normal power supply (50Hz or 60Hz) to another frequency power by inner power semiconductor on/off behaviors, to control electric motors in variable speed operations.

How many Hz is a 3 kW inverter?

2.2kW 3hp frequency inverter with rated current 17A for sale, input voltage single phase AC 220V±15%, input frequency 47~63Hz. With a start frequency of 0.4Hz~20.00Hz, the inverter's speed adjustment range reaches 1:50.

What is a high frequency inverter?

Rated current 7A, input voltage single phase AC 220 ± 15%, and output voltage 1 phase. High-frequency inverter with output frequency 0~1000Hz has start frequency 0.40Hz~20.00Hz. Widely used in refrigeration systems, industrial equipment and mechanical engineering.

What is the speed adjustment range of a variable frequency inverter?

With a start frequency of 0.4Hz~20.00Hz, the inverter's speed adjustment range reaches 1:50. By changing the frequency and voltage supplied to the motor, the variable frequency inverter can achieve stepless speed regulation of the motor.
