L3-300N-048 300W 48V Isolated Constant Voltage LED Driver

L3-300N-048 is a 300W 48V isolated constant-voltage LED driver from the FAHOLD L3 Series. Designed around a single high-current output, it accepts 100-277Vac and delivers a regulated 48Vdc / 6.25A DC output. The L3 platform is intended for professional signage, advertising, LED strip and landscape lighting projects that require a compact enclosed power supply with high efficiency and stable constant-voltage performance.

300W 48V Isolated Constant Voltage LED Driver

For engineers, sign manufacturers and project buyers, L3-300N-048 fits specifications calling for a 300W 48V LED driver, 100-277V AC to 48V DC LED power supply, single-output constant-voltage LED driver or non-dimmable LED power supply for signage lighting. The L3 Series uses an isolated constant-voltage architecture and supports off-line programming, giving OEM and project teams a practical platform for fixed-output LED systems where dimming is not required.

The higher output capacity is intended for larger signage, extensive LED strip installations and centralized constant-voltage lighting systems with substantial load requirements. The 48V DC output is appropriate for higher-power LED systems, long linear-lighting runs and large signage installations where reduced current can improve power-distribution efficiency.

Electrical and Project Selection Considerations

The key specification points for L3-300N-048 are its 300W maximum output, 48V constant-voltage output, 6.25A current capacity, power factor of >0.95 and typical efficiency of 94%. The enclosure measures 255×72×32 mm. The L3 platform includes SCP, OVP, OTP and OLP protection functions and is presented in the product catalog as an IP67/IP68 high-protection-class LED driver for dry, damp and wet-location applications.
