Constant Voltage LED Drivers
On the other hand, constant voltage drivers are designed for LEDs that require a fixed output voltage with a maximum output current. LED lights that operate with a constant voltage driver require a consistent amount of output voltage, typically 12V DC or 24V DC. This type of driver receives a standard voltage, around 120-277 Volts in the form of alternating current voltage (VAC) which the driver converts to a low direct current voltage (VDC). These drivers will maintain a constant voltage as long as the current stays below its maximum amperage rating. Constant voltage applications include under cabinet lights, under stair lighting, strip lights, and rope lights.
