L3-400N-036 400W 36V Isolated Constant Voltage LED Driver

L3-400N-036 is a 400W 36V 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 36Vdc / 11.11A 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.

400W 36V Isolated Constant Voltage LED Driver

For engineers, sign manufacturers and project buyers, L3-400N-036 fits specifications calling for a 400W 36V LED driver, 100-277V AC to 36V 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 36V DC output supports higher-voltage constant-voltage LED assemblies used in commercial signage and specialized linear lighting systems.

Electrical and Project Selection Considerations

The key specification points for L3-400N-036 are its 400W maximum output, 36V constant-voltage output, 11.11A current capacity, power factor of >0.95 and typical efficiency of 93%. The enclosure measures 251×85×41 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.
