The LED waterproof power supply is a kind of LED driving power supply, which is a voltage converter that converts the power supply into a specific voltage and current to drive the LED to emit light. The output of the LED driving power supply is mostly variable with the forward voltage drop of the LED. Constant current source that changes voltage.

If the 60W LED waterproof power supply is connected in series, the brightness of the LED can be kept consistent under any working conditions. The current accuracy depends on the accuracy of the regulator's feedback threshold and is not affected by the change of the LED forward voltage.

When the various parameters in the voltage stabilizing circuit are determined, the output voltage is fixed, but the output current changes with the increase or decrease of the load. The voltage stabilizing circuit is not afraid of load opening, but it is strictly forbidden to short-circuit the load and drive it with the stabilizing drive circuit. LED, each string needs to add a suitable resistance to make each string of LED display brightness level, the brightness will be affected by the voltage change from the rectification.
