Common Precautions
Engineering Data
Derating Curves (Standard Mounting)
Front-mounting, DIN Rail mounting, Bottom-mounting,
Side-mounting
Note: 1.
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
in the above graph).
2.
If there is a derating problem, use forced air-cooling.
3.
(For Customers using 100-W type for a DC Input)
When using an input voltage of less than 100 VDC, reduce
the load calculated with the above derating curve by at least
the following coefficients.
When using a voltage exceeding 340 VDC, the ambient
temperature should be 60
°
C or less.
Note: 1.
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
in the above graph).
2.
The ambient temperature is defined at a location 50 mm
forward from the center of the front surface of the product.
3.
(For Customers using 300-/600-W type for a DC Input)
Reduce the load calculated with the above derating curve
by at least the following coefficients.
Front-mounting, DIN Rail mounting, Bottom-mounting
Horizontal-side-mounting
Note: 1.
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
in the above
graph).
2.
If there is a derating problem, use forced air-cooling.
3.
(For customers using 150-W type for a DC Input)
When using an input voltage of less than 100 VDC, reduce
the load calculated with the above derating curve by at least
the following coefficients.
When using a voltage exceeding 340 VDC, the ambient
temperature should be 60
°
C or less.
