24V DC / 400W Constant-Voltage LED Driver

Model H-PF-24V400W supplies regulated 24V DC power for compatible LED lighting systems. It combines an IP67-rated enclosure, active power-factor correction and a low-profile 35mm body. Installation and all line-voltage connections must be completed by a qualified electrician in accordance with the markings on the actual unit and applicable electrical codes.

• 24V DC constant-voltage output; 400W maximum rated power.
• IP67-rated enclosure for protection against dust and water ingress. Connections and installation details still require suitable weatherproofing.
• Active PFC: PF ≥ 0.98 at 115VAC and PF ≥ 0.95 at 230VAC.
• Over-current, over-voltage and short-circuit protection.
• Low-profile 35mm body.
• STONOVIA warranty: 1 year. Manufacturer-stated service life above 50,000 hours.

With the STONOVIA V2-X controller, each 12 × 24-IN Flex LED Sheet is limited to 24W maximum total output. One 400W driver can support up to 10 LED sheets: 10 × 24W = 240W, leaving 160W of rated driver capacity before controller and wiring losses.

The sheet has cool-white and warm-white channels, each identified as 24W, but the V2-X controller shares the available output between those channels. Therefore, “24W + 24W” does not mean 48W simultaneous consumption in the STONOVIA system.
