Overview

The AL808 series covers process control, AL810 single-phase SCR phase-angle control and AL830 three-phase SCR phase-angle control. These diagrams show typical heating power-control schemes for industrial temperature systems.

AL810 Phase-Angle Output

AL810 can output phase-angle trigger pulses to drive a single-phase SCR power module for stepless AC voltage regulation.
