A constant voltage (CV) LED driver is an electronic device that provides a stable, fixed output voltage to an LED lighting system, regardless of fluctuations in the electrical load or input supply.
Key Characteristics of Constant Voltage Drivers
Fixed Voltage, Variable Current: A CV driver maintains a constant voltage, typically 12V DC or 24V DC, and will supply an output current up to its maximum rating, which varies based on the needs of the connected LED lights.
AC-to-DC Conversion:It converts the higher-voltage alternating current (AC) from the main power supply (like a wall outlet) into a lower, set direct current (DC) voltage suitable for LEDs.
Application: These drivers are commonly used with LED fixtures that have built-in current regulation (often with resistors), such as LED strip lights, LED signage, and under-cabinet lighting.
Simple Installation:CV-driven systems are typically wired in a parallel configuration, which makes the setup less complex and allows for flexibility in the length or number of connected LED units, as long as the total current draw remains within the driver's maximum limit.
