Omron S8VM - Engineering Data; Derating Curve

Switch Mode Power Supply S8VM 9
Engineering Data (15-W, 30-W, 50-W, 100-W, 150-W Models)
■ Derating Curve
300W/600W/1,500W
Note: Refer to page 15.
Note: 1. Internal parts may occasionally be deteriorated or damaged. Do not use the Power Supply in areas outside the derating curves (i.e., the area shown by
shading A in the above graphs).
2. If there is a derating problem, use forced air-cooling.
3. When mounting two or more Power Supplies side-by-side, allow at least 20 mm spacing between them. Multiple 100- and 150-W models cannot be used
side by side. Be sure to install the Power Supplies as far away from heat-generating sources as possible. As a reference value, allow at least 50 mm spacing
on the right and left sides. If only 20 mm spacing is allowed, use the Power Supply at a load ratio of 80% or less.
4. When using 150-W models for a long period of time at an input voltage of 90 VAC or lower, reduce the load to 80% or less of the above derating curves.
