  • Product description

    Dimmable LED power supply | 12 V DC | 250 W | 20.8 A | IP20 | 287×50×30 mm | 4779041468570

    Dimmable / adjustable 12 V DC power supply designed for compatible LED strips, LED modules and other 12 V DC equipment. Rated power – 250 W, maximum stated output current – 20.8 A. The slim 287×50×30 mm housing is convenient where installation width or height is limited, while the IP20 protection rating means that the unit should be installed in a dry environment protected from water and condensation.

    Key point

    This power supply is intended for 12 V DC systems whose total load does not exceed the limits permitted by the manufacturer. When designing the system, not only the 250 W rating should be considered, but also the actual LED load, current on the 12 V side, conductor cross-section, voltage drop, installation location, cooling conditions and the specific dimming method.

    Operating principle

    The power supply is intended to provide 12 V DC to compatible LED equipment. The connected load draws only the current it requires, up to the permitted limit of the power supply. The stated 20.8 A value represents the maximum stated output current, not a constant current that is always supplied.

    12 V × 20.8 A equals approximately 249.6 W, so the current and power ratings are logically consistent. When designing the system, it is necessary to consider not only the theoretical maximum power but also the actual continuous load, ambient temperature, heat dissipation and the operating requirements specified by the manufacturer.

    Why is this power supply useful?

    The 250 W power class is suitable for higher-power 12 V LED systems, while the 287×50×30 mm housing format is convenient for narrow installation spaces. The power supply is specified as dimmable / adjustable. Before designing brightness control, the exact control interface and compatible dimmer must be checked in the manufacturer's technical data.

    Important for designers and electricians

    Before including the power supply in a technical design, the input voltage range, frequency, output type, dimming / control technology, efficiency, power factor, operating temperature and integrated protection functions of the specific product must be checked. These parameters are intentionally not assigned here until confirmed in the manufacturer's technical documentation.

    250 W and 20.8 A – what does it mean?

    At a 12 V DC output, 20.8 A corresponds to approximately 250 W:

    12 V × 20.8 A ≈ 249.6 W

    The actual current drawn from the power supply depends on the connected load. A lower-power LED system will draw less current, while the current on the 12 V side increases as the load approaches the maximum power.

    How to select according to LED strip power?

    The total LED strip load is calculated from its power per metre and the total installed length.

    Calculation principle: LED strip power, W/m × total length, m = total LED load, W.

    For example, if the LED strip power is 10 W/m, a 10 metre length gives a theoretical load of approximately 100 W. During design, not only the total power but also the manufacturer's permitted continuous loading of the power supply should be taken into account.

    Voltage drop is also important in longer 12 V circuits. If an LED strip is supplied only from one end, longer runs may develop a noticeable voltage difference and a reduction in light intensity. In such cases, power may need to be supplied from several points or larger-conductor cables may be required.

    Main functions

    • Power supply for 12 V DC equipment.
    • 250 W rated power for higher-power 12 V LED systems.
    • Stated output current up to 20.8 A.

    • Furniture, shelf and niche lighting.
    • Commercial interior LED lighting.
    • Display and showcase lighting.
    • Architectural indoor lighting.
    • Other compatible 12 V DC equipment where load and control requirements match the power supply parameters.

    Use by requirement

    For LED installers
    A 250 W power supply may be used for larger 12 V LED systems when the total load and cable parameters have been calculated for the specific installation.
    For electricians
    Output current up to 20.8 A requires appropriate selection of conductor cross-section, connectors, terminals and protection solutions on the 12 V side according to the actual load.
    For designers
    Before specification, the input parameters, output type, dimming interface, ambient temperature and manufacturer-declared protection functions should be checked.

    Practical application

    When designing a 12 V LED strip system, the total power of all connected strips or modules is calculated first. The power supply is selected according to the total load, while the conductor cross-section is selected according to current, line length and permissible voltage drop. If the system load complies with the permitted operating conditions of this 250 W power supply, it may be used as the system power source while ensuring an appropriate installation location, adequate heat dissipation and compatibility of the control equipment.

    Why is conductor cross-section important on the 12 V side?

    At low voltage and relatively high power, the current can be significant. A current of up to 20.8 A means that the selection of conductors, connectors and terminals on the 12 V side is an important part of the system design.

    An undersized conductor or an excessively long cable route may cause greater voltage drop, additional power losses and heating of conductors and contacts. The conductor cross-section should therefore be calculated according to the actual current, route length, installation conditions and permissible voltage drop.

    FAQ

    1. What is the output voltage of this power supply?
    The output voltage is 12 V DC.
    2. What is the maximum stated output current?
    Up to 20.8 A. The actual current depends on the connected load.
    3. How much LED strip can be connected?
    This depends on the power of the specific LED strip in W/m. The total load should be calculated from the strip's power per metre and total length, and compared with the permissible load of the power supply.
    4. Can it be installed outdoors or in a damp room?
    The IP20 enclosure does not protect against water ingress and is not intended for direct exposure to moisture. A suitable protective enclosure or a power supply with a higher IP rating is required for such environments.
    5. How is LED brightness controlled?
    The power supply is specified as dimmable / adjustable, but the exact control method – for example phase-cut, 0–10 V, PWM or another interface – must be verified from the manufacturer's technical documentation before selecting a dimmer.
    6. Why is conductor cross-section important on the 12 V side?
    At 12 V and high power, circuit current can be significant. An undersized conductor increases voltage drop, power losses and the risk of heating in conductors and contacts, so the conductor cross-section must be selected according to the actual load and route length.
