LED drivers (also known as LED power supplies) provide LEDs with the electricity they require to function and perform at their best. As most places run on higher voltage, alternating current, and LEDs run on low voltage, direct current, LEDs require drivers for two purposes: To convert higher voltage, alternating current to low voltage, direct current and to keep the voltage and current flowing through an LED circuit at its rated level.You may also need to purchase a separate driver when an LED fails before its rated lifetime. When an LED fails prematurely it is often the fault of the driver. So replacing an LED driver can save you the hassle and cost of unnecessarily replacing a perfectly good LED.
What LED driver do I need?
There are three types of LED drivers: constant-current, constant-voltage, and AC LED drivers. The driver you need depends on the operating specifications of your LED. To begin your selection process, look at your LED (or the LED driver that you are replacing) and select the appropriate voltage range.
- If one output voltage is specified, you need a constant-voltage driver.
- If there is a range of output voltages, you need a constant-current driver.
- If an AC voltage input is specified, you need an AC LED driver
