Zero-crossing switch-on

Suggested applications:

• Lamp inrush current reduction (CFL - Compact

Fluorescent energy-saving Lamps and similar)

• Heater control

• Solenoid, contactor driver

Random switch-on

Suggested applications:

• Finer control requiring short operate time

(specially motor control)

• AC Input phase different from AC Output phase

• 3-phase general purpose
