L3 High-Power Isolated LED Sign Power Supply
High-power isolated single-output constant-voltage LED power supply with 12V / 24V / 36V / 48V options, high-current output and IP67 / IP68 protection for commercial signage and demanding fixed-output lighting projects.
High-Power Isolated LED Power Supply for Commercial Signage
The FAHOLD L3 Series is a high-power isolated single-output constant-voltage LED power supply platform for commercial signage, advertising lighting and other fixed-output LED systems. The 2026 V1.4 technical table covers 100W to 1200W with 12Vdc, 24Vdc, 36Vdc and 48Vdc output options. Model-specific output current reaches up to 25A, giving sign manufacturers and OEM fixture teams a broad power platform for high-current constant-voltage loads.
The series combines isolated architecture, high efficiency and IP67 / IP68 protection for dry, damp and wet locations. Offline programming supports product configuration while the operating platform remains non-dimmable. SCP, OVP, OTP and OLP protection functions are integrated, and the specifies a 5–7 year warranty plus an optional UL junction box.
