Overview

A high-performance 30 kW (40 hp) frequency inverter, offering three-phase voltages of 240V, 420V, and 480V. Rated current is 60A for 380V-480V and 112A for 220V-240V. It can handle 150% overload for 1 minute and 180% for 3 seconds. The 30 kW 3-phase inverter operates at (-10℃, 40℃), and derate by 5% for every 1℃ increase if the ambient temperature exceeds 40℃.

Feature

Three-phase inverter with built-in RS485 communication port, advanced modular design, strong load capacity, stable and durable.
The 30kw variable frequency drive's multi-vent cooling design helps protect the inverter better.
High-performance 40hp frequency inverter equipped with a clear LED digital display, rotary speed control, one-button start, and one-button stop, all completed instantly.
The automatic voltage regulator (AVR) of the 30kw inverter drive maintains constant output voltage during power supply voltage fluctuations.
The 3-phase variable frequency drive can automatically limit operating current to avoid frequent overcurrent trips.

Details

Multiple Function Keyboard

The multi-function keyboard allows users to fully control the 30kW frequency drive inverter, including start, stop, and acceleration. By pressing the corresponding button, users can ensure that the inverter runs according to the pre-set parameters, or change the machine's operating speed by directly adjusting the output frequency, thus flexibly meeting various practical work needs.

Electronic Screen

The core component of the 30kW variable frequency inverter, the screen, intuitively displays rich operating information to users. This electronic display screen has a real-time monitoring function, which can clearly display the dynamic waveforms of the input and output voltage and current of the three-phase inverter, making it easy to handle abnormal operations promptly.

Rugged Casing

The 30kW variable frequency drive inverter's casing is cleverly designed and rugged, effectively protecting the internal precision circuits and electronic components from external environmental factors. It also ensures the high safety, stability, and long-term reliability of the equipment during operation, effectively guarding its internal core components.
