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.
AL830 Three-Phase Control
AL830 outputs three-phase phase-angle trigger pulses and can be used with delta or star connected SCR power circuits.
