Product Introduction
Tapped transformer rectifier is a rectifier composed of tapped transformer, main power transformer and rectifier bridge main components. It is generally divided into coarse adjustment, medium adjustment and fine adjustment.The output voltage can be divided into 16 steps, 25 steps and 64 steps by the combination of gears.
Tapped transformer rectifier is a fully open bridge rectifier, and its working efficiency can reach more than 80%. Tapped transformer rectifier without cumbersome electronic circuit, equipment failure rate is very low, even without professional electronic technology of the field staff, after a simple training can be skilled operation and maintenance.
- product feature:
- The circuit structure of tapped transformer rectifier is relatively simple. By using components such as tap transformers, its cost may be relatively low. Meanwhile, due to its relatively simple structure, it is also relatively easy to maintain, and general technicians can more easily understand and master its maintenance methods.
- Tapped transformer rectifier has high flexibility in some specific application scenarios. For instance, in situations where the potential and current requirements are relatively fixed but need to be adjusted within different ranges, tapped transformer rectifier can meet the demands simply by switching the taps without the need for a complex adjustment process.
- The magnetic circuit structure of the tapped transformer rectifier is relatively stable. As long as the quality is guaranteed during the design and manufacturing process, it can operate stably for a long time under normal working conditions. Meanwhile, if reliable rectifier diodes and other components are adopted in the rectifier part, the stability of the rectification effect can also be guaranteed, thereby making the entire tapped transformer rectifier have better stability and reliability.
