Why should you choose an YSD led power supply? First, you need to know what this power supply is capable of. You will get to know what class it comes in, what its IP rating is, how long it can last, and how much it costs. Once you have a basic idea of these criteria, you’ll be able to choose the best YSD led power supply for your needs.
Class II rating
One of the things to keep in mind when purchasing a LED power supply is its ingress protection (IP) rating. This rating is comprised of a two-digit code that indicates how much solid and liquid the product can withstand. As the number increases, the LED power supply will be more resistant to damage from small objects. However, there are some important things to look for in a Class II LED power supply.
This power supply operates over a wide range of input voltages and operates at up to 305 volts AC. This type of LED power supply dissipates eight watts, leaving 72 W for the system’s requirements. It measures 101.6mm in diameter and 50.8mm in height. It operates within a wide temperature range, from -40degC to 70degC. The power supply also has a 0.5-A local cooling fan output. Its thermal derating curves show that it is capable of handling temperatures ranging from -30degC to 70degC. Additionally, it features a mechanical drawing for mounting standoffs.
Ingress protection (IP) rating
The IP rating of an YSD LED power supply indicates its resistance to water ingress, dust, and other solids. The first digit of the rating indicates its resistance to water jets of varying intensity, angle, and depth. The second digit indicates its resistance to different pressures. If the IP rating is less than or equal to 6, the unit is not protected against water.
The IP Code stands for Ingress Protection Rating. This is an internationally recognized classification system for electrical enclosures. It expresses protection from water and moisture. The IP rating chart is a more detailed description than a product’s marketing term, which is the degree of protection it provides. IP67 rated parts can withstand a 1-meter-deep water immersion for at least 30 minutes.
Long service life
LED lamps usually have short service lives. This is because the voltage they receive is ten times higher than the power supply’s rated voltage. In addition, the peak current produced by LEDs can be hundreds of times higher than the output voltage. To prevent this problem, the power supply’s rated voltage is multiplied by a factor called the life of the LEDs. But that doesn’t mean that LED lamps cannot be used past their lifespans.
LED lamps also need good thermal management. However, increased dissipation can result in their failure. So, power supply designers should focus on improving the thermal performance of their LEDs. During prototype testing, the capacitors’ case temperature should be compared to the specifications of the manufacturer. If necessary, higher temperature capacitors must be selected. Aluminum electrolytic capacitors are suitable for power supply designs because of their low cost and high capacitance per volume. In addition, they have excellent ripple current performance and can withstand transient overvoltage without catastrophic failure.
Inexpensive
A low-cost LED power supply can be a great way to get the most out of your LED lighting project. LEDs can be quite expensive, but thanks to LED drivers, it doesn’t have to be. Diode LED makes a wide range of LED drivers and power supplies. These include dim-to-dim, 0-10, and MLV. Below, we’ve outlined some of the features to look for in an inexpensive LED power supply.
Linear LED power supplies convert unregulated DC voltage to a regulated DC voltage using a linear regulator. These power supplies are very similar to switching type buck regulators and feature an error amplifier and pass transistor to monitor reference/feedback difference. A linear power supply has a minimum dropout voltage. However, the supply is more expensive than a switching-type buck regulator, so you’ll need to carefully consider the voltage source.
Conclusion
When you’re using an LED, you need to be aware of the current it produces. LEDs are incredibly sensitive to current fluctuations, so the power supply must be designed to prevent these fluctuations. A power supply should only deliver the voltage you need and not more. LEDs that need a higher voltage than they’re capable of handling need a constant current power supply. If you need a constant current supply, check its output tolerances and current ripple. It should also protect LEDs from Transient Peak Failure, which can lead to LEDs destroying themselves.
To protect your LEDs from overheating, the voltage you supply must be less than the maximum current allowed by the LED. The maximum forward current of a standard 5mm diameter LED is 20mA, but you can use as little as ten or fifteen milliamps for most circuits. For calculating the required resistor value, you must convert the current from mA to A by multiplying the current by 1000. When deciding on a resistor value, you must consider that a higher resistor value will lower the brightness of the LED.
