The PAC15B Trigger/Trigger Board
The PAC15B intelligent SCR trigger is easy to operate and fully functional.
It features a three-color LED light, making the working status clear at a glance, and can be widely used in various industrial fields for resistive loads.
Key features: It can be flexibly configured for phase-shift voltage regulation, zero-crossing power regulation, or cycle power regulation.
