L3-1K2N-048 1200W 48V Isolated Constant Voltage LED Driver

L3-1K2N-048 is a 1200W 48V isolated constant-voltage LED driver from the FAHOLD L3 Series. Designed around a single high-current output, it accepts 120-277Vac and delivers a regulated 48Vdc / 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.

1200W 48V Isolated Constant Voltage LED Driver

For engineers, sign manufacturers and project buyers, L3-1K2N-048 fits specifications calling for a 1200W 48V LED driver, 120-277V 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.

This high-power configuration targets large-format signage, long-distance linear LED systems and demanding commercial installations where a single high-current output is preferred. 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 L3-1K2N-048 are its 1200W maximum output, 48V constant-voltage output, 25A current capacity, power factor of >0.95 and typical efficiency of 94.5%. The enclosure measures 488×90×49 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.

Relevant long-tail search terms for this model include 1200W 48V constant voltage LED driver, high current LED power supply, isolated LED driver for signage, single output LED driver, waterproof LED power supply for LED strip lighting and 120-277V AC LED driver. FAHOLD specifies a 5-7 years warranty warranty range for the L3 Series.
