The Fibramérica FAB-QYGD-DHS Series is an IP68-rated PWM solar charge controller with an integrated DC-DC boost converter and constant-current LED driver, designed for solar-powered LED lighting applications.
Combining battery charging management and LED lighting control in a compact, waterproof enclosure, the series provides adjustable output settings, programmable multi-stage dimming, and wireless infrared remote configuration. Its integrated constant-current LED driver delivers efficient and regulated power to connected lighting systems.
The controller supports configurable lithium battery charging parameters, including ternary lithium and lithium iron phosphate (LiFePO4) batteries, and incorporates multiple electrical protection functions to enhance operational reliability.
With its integrated design, flexible lighting control, and IP68 protection rating, the FAB-QYGD-DHS Series offers a practical solution for standalone solar lighting installations operating in demanding outdoor environments.
