The VFD-EL inverter series is a new generation of AC drive that has various performance capabilities. This device has an internal EMI filter and RFI switch, it has high accuracy in detecting the amount of current and is protected against motor overload, this drive has an internal keypad that is connected to the inverter.

## Features:

1. It has an output frequency of 0.1~600Hz
2. It has an adjustable V/F curve with three adjustment points
3. It has internal PID feedback control
4. With an internal EMI filter (for 230V single-phase and 460V three-phase models)
5. Ability to use RS-485 (RJ-45) connection line with Modbus protocol
6. It has optional communication modules for multiple communication protocols, for example, Profibus, Devicenet, LonWorks and CAN open.
7. Functionality with full protection

## Applications:

Small size fans and pumps, blowing machines, conveyor belts, simple DIV process equipment

### Inverters:

Inverter or AC drive is a device that can be used to control the speed of a three-phase AC motor without reducing the power and torque of the motor.

### Types of inverters in terms of input:

Inverters are classified into three-phase and single-phase categories in terms of input. Of course, their outputs are all three phases.

### What are the types of inverters in terms of application?

In terms of applications, inverters are divided into different categories. Inverters are used to start pumps, fans, elevators, cranes, conveyors, extruders, etc. Variable torque inverters are used for pumps and fans, constant torque inverters are used for elevators, conveyors and cranes, and PG feedback inverters are used for extruders.

## Advantages and uses of inverter:

1. Engine speed regulator (speed control)
2. Easily change the direction of rotation without the need for a contactor
3. Turning on and off the engine without the need to disconnect and connect the main power
4. Reducing mechanical shocks and thus increasing the useful life of the mechanical part
5. Protecting the motor against voltage increase and preventing damage to the motor
6. Soft launch without any impact
7. Motor protection against overclocking


### In general, inverters are used in three areas:

1. Constant torque activities such as mixers, extruders
2. Constant power activities such as traction and mechanical devices
3. Variable torque activities such as fans and pumps
