The 4.5 Volt power supply has a wide range of applications, but it is most commonly used for connecting LED screens and LED lighting structures. The main function of such devices is to convert and stabilize the input voltage from 90–264 V to 4.5 V. Using this power supply extends the service life of lighting and other devices, prevents premature changes in light output, and eliminates flickering and pulsation of diodes in LED strips. You can always purchase 4.5 V power supplies with different current ratings in the Discon online store. Our specialists can help calculate the necessary parameters for any electronic component and select the most suitable model.
4.5 V Power Supply: Features and Types
On city streets, you can see illuminated signs, advertising screens, and various types of lighting everywhere. Such LED products can perform their functions reliably and remain durable only when connected through a special transformer device, that is, through a 4.5 Volt power supply.
Currently, domestic and international manufacturers offer several types of 4.5 V power supplies:
- Plastic housing: This is a sealed adapter with compact dimensions and a presentable appearance. It can be used to power garlands and furniture lighting. Models of this type have limited power and may experience heat dissipation issues.
- Aluminum housing: These sturdy and reliable devices include protection against overheating and short circuits. The housing is resistant to moisture, temperature fluctuations, UV, dust, and dirt. Such models are suitable for connecting LED screens in advertising banners, light panels, shop windows, and exhibition installations.
4.5 V power supplies can operate at temperatures from -30 °C to +50 °C. If the chosen model has a current rating of 35 A, it can be used even at +65 °C.
How to Install 4.5 V Power Supplies
Power supplies may heat up during operation, so manufacturers design a cooling system. It can be active or passive. In active cooling, a built-in fan ensures proper air circulation under the housing. In passive cooling, airflow over internal components occurs through perforations on the housing.
Perforated units should be installed in well-ventilated areas, away from moisture and direct contact with any liquids. Perforated devices are not suitable for aggressive environments. Power supplies with active cooling are usually more protected from external factors, so there are no strict recommendations for installation location. However, such models typically do not allow adjustment of output voltage.
