Overload Protection
The load and the Power Supply are automatically protected from
short-circuit currents and overcurrent damage by this function.
Overload protection is activated if the output current rises above
105% of the rated current.
When the output current returns within the rated range, the overload
protection is automatically cleared.
The values shown in the above diagrams are for reference only.
Note: 1. If the Power Supply has been short-circuited or supplied
with an overcurrent longer than 10 seconds, the internal
parts of the Power Supply may occasionally deteriorate or
be damaged.
2. Internal parts may possibly deteriorate or be damaged if the
Power Supply is used for applications with frequent inrush
current or overloading at the load end. Do not use the Power
Supply for such applications.
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 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 three
minutes and then turning it back ON again.
The values shown in the above diagrams are for reference only.
Note: Do not turn ON the power again until the cause of the
overvoltage has been removed.
Overheat Protection (S8FS-C350 Only)
If the internal temperature rises excessively as a result of fan failure
or any other reason, the overheat protection circuit will operate to
protect internal elements. Reset the input power by turning it OFF for
at least three minutes and then turning it back ON again.
