Standard mounting
Face-up mounting
Note: 1. Use standard mounting only. Using any other mounting
method will prevent proper heat dissipation and may result
in deterioration or damage of internal elements. Or, the re-
maining service life notice function cannot work properly.
2. If there is a derating problem, use forced air-cooling. The
ambient temperature is specified for a point 50 mm below
the power supply.
I Overload Protection
The Power Supply is provided with an overload protection function
that protects the load and the power supply from possible damage by
overcurrent. When the output current rises above 105% min. of the
rated current, the protection function is triggered, decreasing the out-
put voltage. When the output current falls within the rated range, the
overload protection function is automatically cleared.
I Overvoltage Protection
The Power Supply is provided with an overvoltage protection function
that protects the load and the Power Supply from possible damage
by overvoltage. When an excessive voltage is output, the output volt-
age is shut OFF. Reset the Power Supply by turning it OFF for at
least three minutes and then turning it back ON again.
