The Mean Well HT SDR-120-24 is a compact, high-efficiency 120W 24V DC DIN-rail switching power supply manufactured by Mean Well Enterprises and integrated into Hatteland Technology (Hattland Display) marine bridge electronics and display suites. Built for high-reliability maritime and industrial automation environments, the unit delivers clean, regulated 24V DC power to marine monitors, panel PCs, navigation processors, and bridge control networks.

Housed in an ultra-slim 40mm metal chassis designed for high-density DIN-rail panel layouts, the power supply incorporates active Power Factor Correction (PFC) and achieves operating energy efficiency up to 91%. Featuring a 150% peak load capability (up to 180W for 3 seconds), it effortlessly absorbs startup inrush surges from connected marine displays and capacitive loads, while internal protection circuitry safeguards against output short circuits, overloads, over-voltage, and thermal over-temperature conditions.

Key Features:
• High-Efficiency Marine Power Output: Provides continuous 120W DC output (24V @ 5A) tailored for commercial vessel wheelhouse monitors and bridge electronics.
• 150% Peak Power Surge Capability: Delivers up to 180W peak output for 3 seconds to handle sudden inrush currents during system boot-up.
• Ultra-Slim Design & Active PFC: Compact 40mm-wide metal chassis with active Power Factor Correction (PF > 0.93) optimizes space and minimizes heat inside enclosed consoles.
• Integrated DC OK Relay Contact: Built-in dry-contact relay signal output enables remote power status supervision via PLC or bridge monitoring networks.
• Comprehensive Marine Protection Suite: Integrated safety features against output short-circuits, constant-current limiting overload (110%–150%), over-voltage, and auto-recovering over-temperature shutdown.
