 · Since LEDs are semi-conductors and operate a little differently than most basic circuits, it’s far easier to simply drive them at their rated current with a constant current driver than it is to try and produce that current by providing a constant www.doorway.ruted Reading Time: 9 mins.  · Constant current type LED driver. The current output by the constant current drive circuit is constant, but the output DC voltage varies within a certain range with the size of the load resistance. The load resistance is small, the output voltage is low, and the larger the load resistance, the output voltage is The higher. Constant current circuit is not afraid of load short circuit, but it is Reviews: 2.  · The maximum current that constant voltage drives can reach is determined by the design parameters and this value is written on the driver. For example; A constant voltage source marked 12 V, 5 A can supply a load with a maximum power of 60 W. In summary; constant current LED driver can output constant current in a certain voltage range. The constant voltage LED driver can provide Estimated Reading Time: 3 mins.

Even though a constant voltage driver may be slightly less efficient, it enables a full flexibility to allow a greater final load size. On the other hand, constant current LED drivers are manufactured to only operate constant current devices with specific ratings, making them the more efficient of the two drivers. Since LEDs are semi-conductors and operate a little differently than most basic circuits, it’s far easier to simply drive them at their rated current with a constant current driver than it is to try and produce that current by providing a constant voltage. Constant Voltage - This type of driver will have a Fixed Voltage Output. This will depend on the LED voltage rating. It will be a fixed output. The current output for the driver will have a max rating. If the circuit does not draw more that what is required it will work. Constant Current - This type of Driver will have a Fixed Current Outp.

7 dic What is a Constant Current LED Driver? Constant current led drivers or power supplies are designed to supply a fixed current mA. Constant voltage LED drivers are the power supplies. The most common power supplies are 12 VDC or 24 VDC. These drivers. In this video, we explain the differences between a constant voltage (CV) and a current controlled (CC) LED tape lighting. Current Controlled.
