L2-400B-024-4F 400W 24V 5-in-1 Dimmable LED Driver

L2-400B-024-4F is a 400W 24V waterproof constant-voltage LED driver from the FAHOLD L2-F Series, developed for professional architectural lighting and commercial LED installations. It accepts 100-277Vac input and provides a regulated 24Vdc / 4A × 4 output. With an IP67 enclosure, Class 2 power-supply design and multi-mode dimming capability, this model is suitable for projects that require a protected 400W 24V dimmable LED driver rather than an open-frame power supply.

400W 24V IP67 Dimmable LED Driver for Architectural Lighting

The L2-F platform supports phase-cut and low-voltage dimming methods listed for the series, including TRIAC, ELV/MLV, 0-10V, PWM and potentiometer control. This makes L2-400B-024-4F relevant to specifications calling for a 5-in-1 dimmable LED power supply, a TRIAC dimmable constant-voltage driver, or a 100-277V AC to 24V DC LED driver. The series is designed for 0-100% dimming and flicker-free operation, supporting smoother light-level control in architectural, display and decorative lighting applications.

This high-output configuration is intended for large architectural and commercial LED installations where high power density and centralized dimming are required within a weather-resistant driver enclosure. The 4-channel output configuration allows the total load to be distributed across multiple LED branches, which can simplify wiring and load planning on larger lighting assemblies. For 24V systems, the higher DC bus voltage is useful for longer LED strip runs and linear lighting layouts, helping reduce operating current compared with an equivalent 12V load.

Electrical and Project Selection Considerations

For engineers, lighting manufacturers and project buyers, the main selection points for L2-400B-024-4F are its 400W maximum output, 24V constant-voltage architecture, 4A x 4 output capacity, power factor of >0.99 and typical efficiency of 93.00%. The enclosure measures 276×67.5×40 mm. The IP67 construction is suitable for applications that need a waterproof LED driver for damp or wet-location installations, while the L2-F protection platform includes SCP, OVP, OTP and OLP functions.
