What is an Inverter/VFD/VSD?Motor speed and torque control can be achieved by using an inverter. Inverters can vary the input frequency and voltage of the motors, resulting in more control, improved efficiency and durability of those systems/appliances if used correctly.
VFD/VSD can be used in any application or appliances where it is necessary to control:

When can I use VSD / VSD / Soft Starter?Inverter, VFD, VSD and Soft Starter most commonly used devices for controlling speed or frequency of electro motors. Examples of some of the applications: • Pumps • Conveyer belts • Agriculture • Watch / jewellery making machinery • Sanding Machines |
How to use VFD / VSD
An advantage of a VFD/VSD is its ability to be programmed. In majority of applications programming is not needed and the use of VFD/VSD can be as simple as turning a knob and controlling the motor speed and frequency. However, for dedicated applications it is possible to program and change the parameters of the VFD to the systems specifications. This flexibility and precision of inverters has allowed them to be popular in many industrial applications.
You can control the speed and run a three phase motor. Digital Display and Easy to use Front Control Panel Most economical IGBT Space vector with:
