7. Derating Curves

The derating curves illustrate the maximum permissible load under varying environmental conditions. Adhering to these curves ensures optimal performance and longevity of the power supply.

ຮູບທີ 3: Derating Curves. This image displays two graphs: "Derating Curve" (Load % vs. Ambient Temperature °C) and "Output Derating VS Input Voltage" (Load % vs. Input Voltage VAC). The first graph shows that the power supply can operate at 100% load up to approximately 50°C ambient temperature, after which the load must be reduced. The second graph indicates that the unit can deliver 100% load for input voltages between 100VAC and 264VAC, with a slight derating below 100VAC.

7.1. Derating Curve (Load vs. Ambient Temperature)

This curve shows the maximum output load percentage that can be drawn from the power supply at different ambient temperatures.

• Up to approximately 50°C, the power supply can operate at 100% of its rated load.
• Above 50°C, the output load must be linearly derated to maintain safe operating temperatures.

7.2. Output Derating vs. Input Voltage

This curve illustrates the maximum output load percentage based on the input AC voltage.

• ສໍາລັບການປ້ອນຂໍ້ມູນ voltages between 100VAC and 264VAC, the power supply can deliver 100% of its rated load.
• Below 100VAC (e.g., down to 85VAC), the output load capacity is reduced.
