Overview

0.75kw frequency drive inverter with V/F control, 120v single phase input to 1ph/3ph 220v output. With an IP20 enclosure rating and air cooling, the frequency inverter runs single-phase and three-phase motors and works at (–10℃, 40℃). Offer RS485 communication interface. Easy to install and operate.

Feature

The variable frequency inverter has an MPPT algorithm that can quickly track the maximum power point of the photovoltaic cell, with an efficiency of >99%.
The frequency drive inverter runs automatically around the clock, and can also be completed manually or automatically, realizing "sunrise work, sunset sleep".
Come with 35 protection functions, a variable frequency drive inverter has automatic short circuit detection after power-on, automatic sleep function, pump dry pump protection, low-frequency protection, overload protection, overcurrent protection, overvoltage protection, undervoltage protection, etc.
With remote control, the variable frequency drive inverter supports RS232/RS485 protocol, terminal control, and analog control.

Details

Digital Display

The electronic screen of the 120v input variable frequency inverter displays clear fonts. The indicators of the frequency drive inverter will display the corresponding inverter operating conditions. It can monitor real-time 0.75kw inverter data changes, and improve safety performance.

Multi-function Button

Equipped with multi-function keys, inverter has menu/exit, forward, up/down keys, stop/reset, etc. The functional keys of the 1 hp variable frequency drive inverters are very convenient for adjusting the 0.75kw operating frequency inverter to three phase parameters and operating status at any time.

Cooling Fan

The cooling fan installed in the 1 hp variable frequency inverter introduces cooling air into the 0.75kw frequency drive inverter, reducing the temperature of the components, protecting the devices from damage, and prolonging the inverter's service life.

FAQ

What would you control with a frequency Inverter?

Motor: This is the most direct and common application of frequency inverters. Through frequency converters, precise control of motor speed can be achieved, thereby adjusting the operating speed, torque, and power of machines or equipment. This control is widely used in many fields such as industrial manufacturing, transportation, energy conversion, building ventilation, etc.
Fans and pumps: In scenarios where precise control of flow or pressure is required, such as HVAC systems, water treatment facilities, etc., frequency converters can be used to control the speed of fans and pumps. This can not only improve the operating efficiency of the system. It can also achieve significant energy-saving effects.
Compressors: In refrigeration and air conditioning systems, compressors are key components. By controlling the speed of the compressor through a frequency converter, the cooling capacity can be adjusted according to actual needs, maintaining the stability of the indoor temperature, and reducing energy consumption.
Conveying equipment: Such as conveyor belts, rollers, etc., are widely used in production lines or logistics systems. Frequency converters can achieve smooth speed adjustment of these equipment to meet the needs of different production or transportation stages.

Solid 0.75kW VFD for light industrial use.

I bought this 0.75kW inverter to run a small 3-phase motor off my 120V single-phase shop power. The setup was pretty straightforward, and the RS-485 interface is handy for tweaking remotely. The PID control makes it great for closed-loop speed control. Satisfied with it.
