DEC series is a full digital electromagnetic speed regulating motor controller with advanced technology, and its performance is 10-25 times higher than JD series; Compact structure, flexible and convenient installation; Powerful functionality, able to replace multiple controllers while maintaining the original price level, greatly reducing the cost of use for customers.
The DEC series controllers include the following five models and nine specifications:
1. DEC8505/10A -<90kW Universal Speed Control Controller
2. DEC8505/10D ------<90kW Multi signal Speed Control Controller
3. DEC1810A ------->90kW Universal Controller
4. DEC8505/10X -------<90kW can be connected to an external potentiometer type speed controller
5. DEC8505/10J -------<90kW can be connected to an external start stop signal speed controller
