When you try to purchase the LED Power Supply for your LED Lights, you’ve come across the terms constant current and constant voltage, if you are not a professional guy, you will no clue what those terms mean. In this post, we will clarify the confusion between constant current and constant voltage.
Constant Current LED Drivers
A Constant Current Driver that the output current is a steady value, which is always used to an LED or LED Array to maximize the lifespan because the LEDs have a power-limiting device in order to prevent LEDs from being overdriven. if the working current is not regulated, the brightness of LEDs can fluctuate and the life span will be shortened. the Constant Current LED Drivers always is used for the LED Lights that require a stable output current and operate within a range of voltages. if you are searching for a driver for the LED Strips with a constant current design or to replace the broken driver, it’s important to verify the output current and working voltage before you purchase one.
Constant Voltage Power Supplies
This type of Power Supply with a stable output voltage can be used to light up the LED Lights that have resistors or constant-current drivers. the products with these current-regulating devices might require working with a constant voltage power supply if the working voltage is not AC110V or AC220V, the LED Strips working always working in DC5V, DC12V or DC24V, you can not connect them to the public power system so that you need an AC DC converter that converts the voltage to the correct voltage. if the working voltage not matched, maybe the LED Lights will be damaged or shorten the lifespan.
if you have working voltage or working current issues with the LED Lights, please do not hesitate to contact us. we will be glad to help you to solve it asap.
