6. Структурная схема

The internal functional blocks of the SP-200-24 power supply are illustrated below, showing the flow of power and control signals.

Малюнак 2: Functional Block Diagram. The diagram shows the input (I/P) passing through EMI filter & rectifiers, PFC circuit, power switching, and then to rectifiers & filter for DC output. Control loops include PWM & PFC control, constant current limiting & detection, and over voltage protection (O.V.P.). Overload protection (O.L.P.) and over temperature protection (O.T.P.) are also indicated.

Key functional blocks include:

• EMI Filter & Rectifiers: Processes the AC input.
• PFC Circuit: Improves power factor.
• Power Switching: Converts DC to high-frequency AC for efficient transformation.
• Rectifiers & Filter: Converts high-frequency AC back to stable DC output.
• PWM & PFC Control: Regulates output voltagе і каэфіцыент магутнасці.
• Схемы абароны: O.L.P. (Overload Protection), O.T.P. (Over Temperature Protection), O.V.P. (Over Voltage Protection), Constant Current Limiting & Detection Circuit.
• Рэгуляванне хуткасці вентылятара: Manages the cooling fan operation.

PFC switching frequency (fosc) is 67KHz, and PWM switching frequency (fosc) is 134KHz.

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.

Малюнак 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.

• Для ўводу тtages 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.

8. Настройка і ўстаноўка

Выканайце наступныя дзеянні для правільнай ўстаноўкі:
