Overview

10 hp frequency inverter, 3 phase inverter 13A at 380V ~ 480V, 25A at 220V ~ 240V. With IP 20 enclosure protection, the variable frequency drive inverter has a cooling fan to keep the interior suitable temperature., suitable for motors, fans, pumps, etc.

Feature

The 3 phase inverter with V/F and Sensorless vector control can provide a standard RS485 communication port. The host computer (PC/PLC) can monitor the inverter in the control system and realize complex control functions such as remote control and fine adjustment.
The variable frequency drive inverter local control panel and remote control panel can work at the same time.
Equipped with RS485 communication mode, the variable frequency inverter has a cooling fan to disperse the internal temperature and prevent damage to internal components.

Details

Multiple Function Keyboard

The multiple-function keyboard of the three phase frequency inverter controls the operation of the variable frequency drive inverter, such as start, stop, and acceleration. You can press the corresponding buttons to make the 3 phase variable frequency drive work according to the set inverter parameters or control the inverter machine's operating speed.

Electronic Screen

The electronic screen of the frequency drive inverter is a key component in the control system, providing users with an intuitive and real-time information display. The electronic screen can monitor the operating status of the 7.5kw 3 phase variable frequency drive in real-time, including input and output voltage, and current waveform, which helps to detect abnormal conditions in time.

Rugged Casing

The 10hp variable frequency inverter's rugged casing plays multiple roles in its design. It is not only about protecting the circuits and internal components inside the device but also about the safety, stability, and reliability of the device. The 3 phase variable frequency drive not only protects the internal circuits and components but also provides safety protection.

FAQ

How efficient is a 3-phase vfd inverter?

The efficiency of a 3 phase inverter refers to the ratio of the output power to the input power in the process of converting DC power into AC power, usually expressed as a percentage. This efficiency is affected by many factors, such as input voltage, output power, operating temperature, load current, load characteristics and topology.
The efficiency of a 3 phase solar inverter is usually between 85% and 98%, and the specific value depends on the technology and quality of the 3 phase variable frequency drive design, input voltage, output power, operating temperature, load current, load characteristics, topology, and other factors.
In practical applications, to improve the efficiency of the three phase solar inverter, it is necessary to select a suitable input voltage and output power range, avoid high temperature environment, and optimize load characteristics and topology.
To improve the efficiency of a high efficiency three-phase inverter, a series of measures can be taken, such as selecting a suitable input voltage and output power range, avoiding a high-temperature environment, and optimizing load characteristics and topology. In addition, advanced control strategies and technologies, such as maximum power point tracking technology and soft switching technology, can also be used to further improve the efficiency of the inverter.
