An LED driver is an electrical device that regulates the power to an LED or string(s) of LEDs. Unlike conventional power supplies, an LED driver responds to the ever-changing needs of the LED, or circuit of LEDs, by supplying a constant amount of power to the LED, as its electrical properties change with temperature. The most important thing for a good constant current driver is, obviously, keeping the current constant. Under heavy electric load, the current may not stay constant.
A key characteristic of any constant current LED driver is its efficiency. Efficiency gives us the amount of input power that can actually be used by the driver, to power the LED. Arraystorm LED drivers have an efficiency of over 80%, making them the best in their class.
The power factor tells us how much load the driver puts on the electrical network. The ideal power factor is 1. Our continuous efforts towards achieving this ideal has resulted in all our drivers having a power factor greater than 0.90.
Our highly reliable drivers reduce the need for inconvenient repairs and maintenance spend. This reliability is attained by using components with a high mean time between failure (MTBF) and very efficient thermal management of the driver.
Our drivers are designed to protect LEDs from surges. Their various inbuilt protections, such as spike and reverse polarity protection, ensure the safe and efficient working of LEDs.
