Accessories for variable transformers, duty cycle controllers
Description
Control unit for motor-controlled variable transformers.
Adjustable power supplies in the mains voltage range as well as in the high-performance range are implemented in the largest states with variable transformers. It consists in the fact that it is not about the perception of adjusting the performance, only one thing belongs to also being constant. For this purpose, the variable transformers are equipped with a motor controller that is controlled by license control electronics.
With this one there is the possibility to take care of a certain control electronics for the control of direct current motors with a permanently excited field.
Advantages
- easy handling
- for voltage stabilizers or as current / voltage regulators
- Installation horizontally or vertically
