MEAN WELL SD-1000L-12 Enclosed DC-DC Converter
The MEAN WELL SD-1000L-12 is a high-performance, industrial-grade enclosed DC-DC converter engineered to deliver a highly stable, regulated 12V DC output at up to 60A. Part of MEAN WELL’s robust 1000W-frame platform, this “step-down” (buck) converter features a wide 4:1 DC input range (19V to 72V DC), making it highly versatile for cleaning up or transforming varying DC voltages from battery banks, solar arrays, telecom networks, and heavy machinery power systems. Built with top-tier protections and integrated active cooling, it is optimized for demanding, mission-critical automation and electrical setups.
Key Features
-
Wide 4:1 Input Range: Accepts nominal inputs across a broad spectrum from 19V to 72V DC, smoothly adapting to fluctuations in input power supply.
-
Heavy-Duty High-Current Output: Consistently outputs a potent 12V DC up to 60A, producing 720W of continuous power (up to 1000W structural peak class footprint).
-
Comprehensive Industrial Safeguards: Outfitted with automatic protections against short circuits, overloads, over-voltages, and over-temperatures.
-
Advanced Monitoring & Control: Features a built-in remote On/Off control toggle, remote sense capabilities for voltage drop compensation, and an Output OK signal for remote status tracking.
-
Forced Air Cooling: Designed with an integrated long-life DC fan ensuring optimal thermal dissipation even under continuous, heavy electrical loads.
-
High Electrical Isolation: Provides 2000V AC input/output isolation to completely shield sensitive low-voltage control circuits from harsh source surges.
