Leading supplier of power control devices CD Automation UK is launching a family of low-cost soft starters for small AC induction motors to the UK market.
DOL Motor Starter is the least complex, least expensive and most basic Starting technique. Besides, it really gives the least temperature ascend inside the engine amid start-up of all the beginning techniques.
This device became known as the silicon controlled rectifier (SCR), or in Europe, the Thyristor ; it is the basis on which all soft starting systems are built.
This project is designed to control the speed of a single-phase induction motor by using operating knob, which is commonly used in home automation applications. The main advantage of these motors is their ability to operate from a single-phase power supply
Most induction motors are started directly on line, but when very large motors are started that way, they cause a disturbance of voltage on the supply lines due to large starting current surges. To limit the starting current surge, large induction motors are started at reduced voltage and then have full supply voltage reconnected when they run up to near rotated speed.

VFDs or variable frequency drives in India are trending as a standard part of marine equipment room packages. Many of them are easy to install and operate; however, manufacturers produce complex designs in order to implement them sophisticatedly.
GEMCO Digital Convertors are dedicated for industrial applications in which good static and dynamic performance and independent controls of speed, acceleration, torque, tension etc. are essential.
An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. An embedded system is designed to run on its own without human intervention, and may be required to respond to events in real-time.
