This product is mainly used for DC motor speed regulation, and DC source voltage regulation. It is widely used in metallurgy, mechanical, and coal industries with a good effect.
It connected with the high power thyristors as a three-phase full-bridge rectifier circuit that adopts the over-current and over-voltage protection for high reliability. It uses the heat pipe technology to change the design solutions of traditional heatsink, to break away the single cooling mode by solely depending on the high air cooling to gain better heat dissipation effect. Due to the use of heat pipe technology, the heatsink can also get satisfied effect even with low speed and low volume motor. It can solve the noise issue of air cooling well.
