Product features

1. Lj-ihrt series intelligent hybrid thyristor switch adopts the industry-leading patented technology of capacitor energy storage leading zero crossing trigger, which ensures lower on-line current value and overcomes the problems of large on-line inrush current, fast mechanical contact burning, adhesion and thyristor breakdown in the market.

2. The world's only thyristor switch without transformer and high-voltage electronic switch triggering inrush current conduction, there is no transformer triggering duty cycle, zero crossing blind area and high-voltage electronic switch breakdown problems.

The thyristor is one of the most advanced thyristor load-carrying methods in the industry.

4. Integrated modular design, small size, simple wiring, easy maintenance. *

5. Protection of quick break, over-current, phase loss, over-voltage, under voltage, etc. *

6. Record fault information to facilitate fault diagnosis. *

7. RS-485 communication, remote monitoring. *

8. Industrial electronic components, super anti-interference photoelectric isolation circuit, to ensure long-term reliability in harsh industrial environment. (Note: if the product features marked above are different from the specific models, the product manual shall prevail. )
