Overvoltage Protection
15-/35-/50-/100-/150-W Models
Consider the possibility of an overvoltage and design the system so that the load will not be subjected to an excessive voltage even if the feedback
circuit in the power supply fails. When an excessive voltage that is approximately 130% of the rated voltage or more is output, the output voltage
is shut OFF, preventing damage to the load due to overvoltage. Reset the input power by turning it OFF for at least seven minutes and then turning
it back ON again.
300-/600-W Models
Consider the possibility of an overvoltage and design the system so that the load will not be subjected to an excessive voltage even if the feedback
circuit in the Power Supply fails. When an excessive voltage that is approximately 120% of the rated voltage or more is output, the output voltage
is shut OFF, preventing damage to the load due to overvoltage (Except 300-W 24V, 48V models ). Reset the input power by turning it OFF for at
least three minute and then turning it back ON again.

Note: Do not turn ON the power again until the cause of the overvoltage has been removed.
Overheat Protection
300-W 5V, 12V/600-W Model
If the internal temperature rises excessively as a result of fan failure or any other reason, the overheat protection circuit will be triggered to shut
OFF the output voltage and simultaneously the protection-ON alarm indicator will be lit. Reset the input power by turning it OFF for at least three
minutes and then turning it back ON again.
