Frequently Asked Questions
1. Select suitable wattage based on customer’s system requirements and application functions. Must also take excess power and driving method into consideration.
2. Based on LED power supply’s operating environment select suitable mechanical type (metal enclosure, plastic enclosure, and open frame PCB) for that environment.
ans:LED power supplies, provide LED displays with the electricity they require to function and perform at their best, much like a ballast does for a fluorescent lamp and a transformer does for low-voltage bulbs. Unlike most bulbs that operate on a higher voltage alternating current, LEDs run on low voltage direct current. Because of this, LEDs need drivers to convert that alternating current to direct current and to keep the voltage flowing through an LED circuit at the rated level that the LED requires.
ans: Constant current power supplys are designed for LED lights that require a fixed output current and a ranged output voltages. This type of driver will have one specified output current labeled in amps and a range of voltages that will vary depending on the wattage rating of the LED. Using a higher amp rate will make the LED brighter; however, it will eventually over-drive the LED which results in reduced life-span and premature failure. Since constant current drivers maintain a consistent brightness, they are often used for signs, back-lighting, and commercial LED displays
ans:There are two main types of LED power supplys: constant current and constant voltage. Each type is designed to operate LEDs with different electrical requirements. If you're replacing a driver, be sure to match the old driver's input and output requirements as closely as possible when choosing a replacement LED power supply.
