Accessories for variable transformers, duty cycle controller
Description
Control unit for motor-controlled variable transformers
Adjustable power supplies in the mains voltage range and in the high-power range are in most cases realized with variable transformers. In most cases, it is not enough to adjust the voltage or power, but also to keep a set value constant. For this purpose, the variable transformers are driven by a motor, which is controlled by appropriate control electronics.
The device described here is such a control electronic for controlling DC motors with permanently excited field.
Advantages
- Easy to use
- For voltage stabilizers or as current/voltage regulators
- Horizontal or vertical mounting
