Description

19R6S3E-900A A frequency converter or variable frequency drive (VFD) is an electrical device that converts a current with one frequency into another current with another frequency. Frequency converters are commonly used to control the speed of motors used to operate pumps and fans. The VFD Speed ​​Controller is a solid-state power electronics conversion system consisting of three distinct subsystems: a rectifier bridge converter, a direct current (DC) link and an inverter.

Advantage

• Save energy and cost.
• A VFD controls a pump motor that normally runs less than full speed.
• Reducing power consumption on a motor running at a constant speed for the same period.
• In addition, it eliminates the need for mechanical drive components, which also helps reduce overall costs.

Disadvantage
