Key Factors to Consider When Choosing a 220V AC LED Driver
- Output Current (Constant vs. Adjustable)
The output current of the driver must precisely match the forward current requirement of your LED array. Most LEDs operate on constant current (e.g., 350mA, 700mA, 1050mA), so selecting a driver that provides a stable and consistent current is critical. Using a driver with too high a current can burn out LEDs, while too low a current results in dim or inconsistent lighting.
Some drivers offer adjustable output current within a specified range, making them versatile for use with multiple LED configurations. These are ideal for installations where different fixtures may require slight current variations, reducing the need for multiple driver SKUs and simplifying inventory management.
- Wattage and Power Output
The driver’s wattage rating should match or slightly exceed the total power consumption of the connected LED load. To calculate the required wattage, multiply the wattage per LED module by the number of modules in the circuit. For example, ten 10W LED strips require a minimum 100W driver.
It's recommended to include a 10–20% safety margin (derating) to prevent the driver from operating at full capacity, which enhances reliability and extends lifespan. Overloading a driver leads to overheating and premature failure, while underutilizing it may result in inefficiency and higher costs.
Many commercial and industrial installations opt for higher-wattage drivers to allow for future expansion without replacing the driver, supporting scalable lighting designs.
