The power supply plays a key role in ensuring that the voltage is properly adjusted to the requirements of a given device. A well-functioning power supply is crucial not only for the proper functioning of devices, but also for ensuring safety. Incorrectly adjusted voltage can lead to damage to the device or even danger to the user, e.g. through overheating, overvoltage or other undesirable phenomena.
The task of each power supply is to convert the alternating voltage (AC) to direct voltage (DC) or adapt the already existing voltage to meet the requirements of the device. This is especially important in the case of electronic devices such as computers, TV sets, smartphones or other similar devices that require a stable and properly configured power source. The power supplies can also convert the supply voltage (e.g. from the mains) suitable for a given type of bulbs, LED strips, light panels and other types of lighting. Thanks to this, we can regulate the current or control the brightness of the light, allowing you to adjust the light intensity to your preferences.
Power supplies may differ from each other, depending on their technical parameters and functions. The type of power supply, power and output voltage or regulation, as well as stabilization are just some of the discrepancies between individual products. What models do we have?
The operation of this type of power supplies is based on the use of a transformer to change the voltage and stabilize the current using a transistor. However, due to – such as low energy efficiency, large size and high heat generation – they are used less and less in modern solutions.
They operate based on voltage converters – they are distinguished by higher energy efficiency, smaller sizes and a lower degree of heat release. They use more advanced electronic circuits that allow for more efficient processing and voltage regulation. Today, the ideal solution for most electrical applications is to choose a 12V or 24V switched-mode power supply – they will work, for example, for tapes or LED drivers.
In addition to traditional solutions, we also offer special purpose power supplies. Those designed for specific applications can be divided into:
Wattage is a key parameter of a power supply as it determines the amount of energy it can deliver to the powered device. It is expressed in watts (W), assuming that 1 W (watt) is the power consumed by a device powered by 1 V (volt) at 1 A (ampere). Calculating the power is simple and you can use the following formula:
This formula allows you to calculate the power of the power supply, taking into account the value of the voltage and current provided by it. The higher the power of the power supply, the more energy it can provide, which is especially important for devices with higher energy requirements.
In practice, the selection of a power supply with the appropriate power is essential to ensure proper operation of the device and to avoid overloading or underpowering. That is why it is so important to check the power requirements provided by the device manufacturer and adjust the power supply to them.
All of these factors affect the performance of power supplies, whether they are switched-mode, conventional, or aggregate. Neither active nor reactive power can be exceeded in any of these devices, as it may result in irreversible damage. To ensure a longer life for your device, it is important to take care of its proper working conditions – overheating will result in permanent damage and compromise safety.
