A constant voltage LED driver is a type of power supply that maintains a steady voltage output, typically 12V or 24V DC, regardless of the load connected to it. Unlike constant current drivers, which regulate the current, constant voltage drivers allow the current to vary depending on the requirements of the LEDs connected.
Constant voltage LED drivers are used in specific applications where LEDs are designed to operate at a fixed voltage. These LEDs usually have built-in current-limiting resistors or internal constant current drivers to regulate the current flow themselves.
Reasons to use constant voltage LED drivers or power supplies:
- Compatibility with certain LED types: Many LED strips, modules, and some types of signage are designed to be powered by a constant voltage source. These LEDs have internal circuitry to manage the current.
- Ease of installation: Constant voltage systems are generally simpler to wire, especially for longer runs of LED strips. You can connect LEDs in parallel, and each LED receives the same voltage.
- Flexibility in length: LED strips designed for constant voltage drivers can often be cut to the desired length without needing to adjust the driver, as long as the total current draw remains within the driver's capacity.
- Cost-effectiveness: Constant voltage drivers are often less expensive than constant current drivers, especially for larger-scale applications.
However, it's crucial to use constant voltage drivers only with LEDs specifically designed for them. Using a constant voltage driver with LEDs intended for constant current can lead to overcurrent and damage the LEDs.
In summary, constant voltage LED drivers are used when the LEDs themselves regulate their current and require a stable voltage supply. They offer simplicity, flexibility, and cost-effectiveness for specific types of LED lighting applications like LED strips and certain signage.
