The Mean Well HT SDR-240-24 is a high-performance 240W 24V DC DIN-rail switching power supply module manufactured by Mean Well Enterprises and integrated into Hatteland Technology (Hattland Display) marine bridge electronics suites. Purpose-built for demanding maritime and heavy industrial applications, the unit supplies clean, regulated 24V DC power to commercial marine displays, bridge navigation computers, PLC control systems, and vessel automation cabinets.

Featuring a compact 63mm-wide metal chassis designed for high-density panel mounting, the power supply incorporates active Power Factor Correction (PFC) and delivers operational energy efficiency up to 94%. Equipped with a 150% peak load capability (up to 360W for 3 seconds), it absorbs cold-start inrush currents from large capacitive and inductive bridge loads, while built-in safety circuitry provides protection against short circuits, overloads, over-voltage, and thermal over-temperature conditions.

Key Features:
• High-Efficiency Marine Power Output: Delivers continuous 240W DC power (24V @ 10A) tailored for commercial vessel bridge equipment and industrial control panels.
• 150% Peak Power Surge Capacity: Provides up to 360W peak output for 3 seconds to handle sudden inrush currents during system boot-up.
• Ultra-High Efficiency & Active PFC: Operates at up to 94% efficiency with active Power Factor Correction (PF > 0.93) to minimize heat accumulation inside sealed cabinets.
• DC OK Relay Status Output: Includes a built-in dry-contact relay signal for remote power status supervision via shipboard alarm or PLC monitoring networks.
• Industrial Marine Protection Suite: Integrated safety protections against output short-circuits, constant-current limiting overload (110%–150%), over-voltage, and auto-recovering over-temperature shutdown.
