619917Z 500W LED Light Engine Circuit Board for IntelliBrite 5G Pool

Please note that this product is not OEM; it is only a compatible replacement part.

only 1pc control broad

Material: Brass

Power: Suitable for 500W pool lights

Application: Replacement driver board for pool LED lights; directly replaces old or damaged lighting engines to restore underwater pool lighting functionality.

Functionality: The driver board stably drives multiple groups of LED chips to emit light, supports brightness adjustment, color switching, and mode grouping control, and features overcurrent, overvoltage, and overheat protection, making it suitable for long-term underwater operation.

Operating Principle: After an external power supply is connected, the onboard voltage regulator and constant-current drive circuits convert the voltage into a working current suitable for the LEDs. They individually control each group of LEDs to illuminate and combine to produce different light colors. The main control circuit receives commands from the controller to switch lighting modes, while the protection circuit continuously monitors electrical parameters and cuts off the output in case of abnormalities to prevent the driver board from burning out.
