力直流安定化電源。 For outputs that are higher than the reference output, a series circuit of a diode, a resistor, and a photocoupler is used to determine the voltage difference between the reference control output circuit and each output.For outputs that are lower than the reference output, a series circuit of a Zener diode, a resistor, and a photocoupler is used to short the output. A multi-output DC stabilized power supply characterized by a protection circuit that stops oscillation in the circuit due to a change in output due to a change in output due to the like.
