Overview

Single phase to three phase frequency inverter, 5.5 kW (7.5 hp), 1-phase 220v, 230v, 240v 50Hz/60Hz input, 3 phase 0-220v output. Come with a cooling fan, 1 phase to 3 phase inverter has LCD to show parameters, and convenient real-time monitoring of working status. Equipped with a Panel speed control knob, the single phase to 3 phase inverter can manually adjust the operating speed.

Feature

Equipped with a cooling fan, the single phase to 3 phase inverter has a strong heat dissipation capacity, which is conducive to maintaining the optimal internal operating temperature and protecting internal parts from damage.
The LCD screen of the 1 phase to 3 phase inverter is moderate in size and has clear fonts. The installation of LCD makes the operating parameter changes more intuitive. The Interior PID controller is convenient for making closed-loop systems of inverter converting single phase to 3 phase.
Come with a panel speed control knob, the operating speed of the variable frequency drive single phase to 3 phase can be adjusted by itself.

Details

Digital Display

The electronic screen of the 5.5kw 1 phase to 3 phase inverter displays clear fonts. The digital inverter indicators of the variable frequency inverter will display the corresponding 5.5kw inverter operating conditions. It can monitor real-time inverter data changes, and improve safety performance.

Multi-function Button

Come with multi-function keys, the inverter single phase to three phase has menu/exit, up/down keys, forward and stop/reset. The functional key of the variable frequency drive single phase to three phase is very convenient to adjust the frequency inverters' parameters and operating status at any time.

Cooling Fan

The intelligent cooling fan installed in the 7.5hp single phase to 3 phase inverter can introduce cooling air into the frequency inverter, which can reduce the 5.5kw variable frequency drive inverter's component temperature, protect the devices from damage, and prolong frequency drive inverter's service life.

FAQ

How to calculate the switching frequency of the frequency inverter?

The calculation of switching frequency is not a simple formula operation but needs to be determined according to the specific frequency converter design and control strategy. Here are some considerations related to switching frequency:

Control algorithm: Different control algorithms (such as PWM control, SVPWM control, etc.) will affect the calculation and setting of switching frequency.
Load characteristics: The type, size and dynamic characteristics of the load will affect the selection of switching frequency.
Efficiency and thermal design: The higher the switching frequency, the greater the switching loss of the power switching components, which will affect the efficiency and thermal design of the inverter.
Filtering requirements: Higher switching frequencies can reduce the size and weight of the output filter, but may also increase harmonics and electromagnetic interference (EMI).
Specifications of switching components: Different switching components have different switching speeds and tolerances, which will also affect the choice of switching frequency.
