Engineering Data
■ Derating Curves
Note: 1. If there is a derating problem, use forced air-cooling.
■ Overload Protection
The Power Supply is provided with an overload protection function
that protects the Power Supply from possible damage by overcurrent.
When the output current rises above 105% min. of the rated current
(100% min. of the rated current for parallel operation), the protection
function is triggered, automatically decreasing the output voltage.
When the output current falls within the rated range, the overload
protection function is automatically cleared.
The values shown in the above diagram are for reference only.

■ Overvoltage Protection
An overvoltage protection function is provided so that excessive
voltage is not applied to the load, e.g., if the feedback circuit in the
Power Supply fails. When a voltage that is approximately 120% 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 1 minute and then
turning it back ON again.
