Triac AC Line Switching
Product Code : JA-PET-1420
The TRIAC AC line switching trainer is a power electronics board for studying the TRIAC as a static switch for AC loads. It covers line-triggered, DC-triggered, self-latching and UJT-triggered switching, including UJT triggering controlled by an external transducer through a transistor. A 40 W lamp shows the switched power, and an isolation transformer protects external instruments that are not isolated (SKU JA-PET-1420).
