Housed in a compact 225 × 124 × 41 mm metal case, it uses an intelligent temperature-controlled built-in fan for forced-air cooling and operates from -30°C to +70°C. Advanced functions include remote ON/OFF, remote sense (compensates up to 0.3V line drop), and DC-OK signal for system monitoring. Protection covers short circuit, overload, over voltage, and over temperature, with shutdown-and-repower recovery. Conformal coating, 3G vibration resistance, OVC III, 5000m altitude operation, and a 3-year warranty make it a rugged high-current 12V power platform.
Massive 12V Output: 92A / 1104W continuous, 138A / 1656W peak for 5s—built for high-inrush industrial loads.
High-Voltage Industrial Input + PFC: 180–305V AC / 255–431V DC, PF ≥ 0.95, 91% efficiency at 12V model.
Smart Forced Cooling: Built-in long-life fan with temperature-based speed control; 41mm low-profile enclosure saves panel space.
Advanced Control Functions: Remote ON/OFF, remote sense, DC-OK signal—ready for PLC/monitoring integration.
Rugged & Certified: Short/overload/overvoltage/overtemp protection, conformal coating, 3G vibration, OVC III, 5000m altitude, IEC/UL 62368-1& 61558, 3-year warranty.
