Mounting
Side mounting is only for S8VK-G015
@@
.
Use a mounting bracket (S82Y-VK15P, sold separately) when the
product is mounted horizontally.
Heat dissipation will be adversely affected. When the product is
mounted facing horizontally, always place the side with label facing
upward.
Overload Protection
The load and the power supply are automatically protected from
overcurrent damage by this function.
Overload protection is activated if the output current rises above
121% of the rated current.
When the output current returns within the rated range, overload
protection is automatically cleared.
Note: 1.
Internal parts may occasionally deteriorate or be damaged
if a short-circuited or overcurrent state continues during
operation.
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. If an excessive voltage that
is approximately 130% of the rated voltage or more is output, the
output voltage is shut OFF. Reset the input power by turning it OFF
for at least three minutes and then turning it back ON again.
Note:
Do not turn ON the power again until the cause of the
overvoltage has been removed.
Inrush Current, Startup Time, Output Hold Time
Note:
Twice the input current or above will flow during the parallel
operation or redundant system.
Therefore, check the fusing characteristics of fuses and
operating characteristics of breakers making sure that the
external fuses will not burn out and the circuit breakers will not
be activated by the inrush current.
