The output voltage is determined by the Zener diode voltage and the voltage drops across the optocoupler photodiode and resistor R1. This technique is lower cost and more accurate , rectifiers with low voltage drops to achieve acceptable load regulation. This simple optocoupler/Zener ... Power Integrations
