■ Overvoltage Protection
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 volt-
age that is approximately 140% of the rated voltage or more is out-
put, 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 three minutes and then turning it back ON again. Alternatively,
turn OFF and ON the remote control signal.
The values shown in the above diagram are for reference only.
Note: 1. Do not turn ON the input power again until the cause of the
■ Overheat Protection
The overheat protection circuit will operate and outputs will be shut
OFF to protect the Power Supply if the ambient temperature rises,
the fan stops, or other errors cause the Power Supply's internal tem-
perature to rise. To reset the Power Supply, leave the input power
OFF long enough for the Power Supply to cool sufficiently and then
turn it ON again. Alternatively turn OFF the remote control signal
long enough to cool sufficiently and then turn it ON again.
■ Peak Output Current
The peak current must satisfy the following conditions. Reduce the
peak current according to the load rate of the derating curve.
