The Fibramérica FAB-QYGD-SDHB Series is an IP68-rated PWM solar charge controller integrating a boost-type constant-current LED driver and programmable lighting control. It is intended for solar-powered LED lighting systems that require regulated light output, battery management and flexible lighting schedules.
The controller provides infrared remote configuration, adjustable LED current and five programmable lighting stages. The series includes configurations for 12V/24V lead-acid battery systems and selected 3-cell ternary lithium or 4-cell LiFePO4 battery packs, with current ratings depending on the chosen version.
The application diagram also illustrates an arrangement involving an external AC-to-DC supply for grid-assisted operation. This is a system integration arrangement, not a claim that the controller accepts 220V AC directly. The electrical configuration must be matched to the battery and LED load before installation.

Technical verification: Values marked † are reproduced as listed and require confirmation: several 4S LiFePO4 figures differ from the corresponding per-cell voltage multiplied by four, particularly the 14.0V overdischarge-protection figure. The model-to-battery compatibility and 24V LED output ratings must also be confirmed for each final configuration. Do not use the flagged values as battery setup instructions until validated.
Our engineering team can confirm compatibility, custom specs and OEM branding options.
