Refer to the Engineering Data section on page 4 for details.
3.
If the V. ADJ adjuster is turned, the voltage will increase by more than 15% of the voltage adjustment range.
Check the output voltage of the power supply when converting the output voltage, and make sure that the load will not be damaged.

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.

Note: 1.
Internal parts may occasionally deteriorate or be damaged
if a short-circuited or overcurrent state continues during op-
eration.
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.

Note: 1.
The maximum ambient temperature for parallel operation is
45°C.
2.
Parallel operation is not possible for an input of 95 to
110 VDC.
3.
Although operation is possible in the (2) portion of the der-
ating curve, performance may be adversely affected, i.e.,
ripple noise may increase.
4.
Internal parts may occasionally deteriorate or be damaged.
Do not use the Power Supply in areas outside the derating
curve (i.e., the area shown by shading (1) in the above
graph).

Note: 1.
Improper mounting will interfere with heat dissipation and
may occasionally result in deterioration or damage of inter-
nal parts. Use the standard mounting.
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.
