LED displays are breaking down barriers to high-density solutions that are lightweight, energy efficient, and customized. This is increasing the demand for power supplies. Let’s look at the details of these LED display power supply.
LED display screen power supplies
The following are characteristics of quality LED power supplies:
High Reliability : Due to the cost and inconvenience of repairing LEDs screen installed at high heights, reliability is paramount.
High Efficiency: LED displays need save energy, so the efficiency of the power supply must be aligned. Higher efficiency means less heat, power loss and temperature.
High power factor: This is essential for aligning to grid requirements and avoiding pollution caused by concentrated loads.
Surge protection: Protect LED displays against potential damage from surges. This is especially important in outdoor settings that are prone to grid fluctuations or lightning strikes.
Protection Functions: Temperature feedback in the output power prevents overheating and meets safety and electromagnetic compatibility standards.
Excellent temperature characteristics: Consistent operation even with high power density or seasonal temperature variations.
Superior Humidity Resistance: Durability against high humidity even in extreme weather conditions.
Strong Interference Resistant: Protects against electrical grid fluctuations, such as lightning, overload voltage, and overcurrent, to prevent any damage.
Type of power supply for LED display screen
A specific power supply is required for LED displays. When selecting a power source for LED displays, you should choose one with a low output voltage but high current (e.g. a 5V/60A application). This is due to the fact that LED chips work at low voltages. White LEDs operate between 2.8-3.3V; red LEDs at 1.8-2V; blue LEDs at 3.0-3.2V; green LEDs at 2.9-3.1V and yellow LEDs at 1.8-2V. LED Display manufacturers choose 5V as their primary power source.
Future LED displays power supplies could shift to 4.5V/4.2V due to the improvement in driver IC efficiency and LED component technology. The next generation of voltages such as 2.5V/3.3V/4V are now being standardised, creating a wide range of products that are in stock. The selection and customization of LED displays is now much easier for customers.
How to Choose High-Quality Power Supplies for LED Display Screens
LED displays will last longer and use less energy if you choose a reliable and qualified power supply.
Look at the craftsmanship: Reputable manufacturers adhere to strict standards of workmanship in order to maintain consistent product quality.
Full Load Efficiencies: The key to efficiency is a higher level of efficiency, which translates into energy savings and cost savings.
The output voltage ripple must be kept to a minimum for LED display equipment to last as long as possible.
Observing temperature during operation: A lower temperature increase enhances the stability and longevity of the power supply. This is usually associated with higher efficiency.
Allowance for Fluctuating currents: LED displays are subject to instantaneous changes in current during video playback. It is important to ensure that the power supply takes this into account for stability and longevity.
Select Higher Rated Models: Choose models that have at least 30% higher output power than necessary to prolong the life of your power supply.
Power supplies can be selected with specific features, such as overvoltage protection, temperature protection, overload protection and power factor correction, based on the application scenario.
Other Factors
Choose power supplies that have a pleasing appearance. This indicates excellent uniformity of component arrays.
Check the efficiency of your power supply. Efficiency is a key factor in assessing energy-saving abilities. It should be above 80% to ensure a reliable power supply when at full load. A higher efficiency requires less active power.
The Power Factor Correction value (PFC) is critical for efficiency. A power supply without PFC may have a PF below 0.6. Low PF values increase reactive power, which leads to significant power losses.
The stability of the power supply will affect the longevity and stability of the LED display. This stability can be seen in the ripples and temperature increase. Power supplies with good stability should have minimal temperature increase and low ripple.
Summary
