SSR40Ph-Ai-Fi semiconductor relays with electronic AC switches, designed for communication of powerful electrical loads with phase regulation for load advance via variable analog or digital signal.
Phase adjustment for load advance (respectively Power) via variable analog or digital signal.
They do not have "zero crossing" (switching on when the mains voltage is switched to zero).
Suitable for control with a microcontroller, via analog signal 0-10V or via PWM 0-1kHz. Manual adjustment via a variable resistor (potentiometer) is also possible.
