The LCM12K-SHF-N is a 12 kW power shelf designed to provide centralized current sourcing for medium to large scale LED lighting and horticulture applications. This 19" 1U rack mount shelf houses three 4 kW power modules with hot plug replacement capability, accepting high-line 600 Vac three-phase input with neutral connection (540 to 660 Vac operating range). The shelf delivers a nominal output voltage of 250 Vdc with adjustable range from 100 to 300 Vdc and maximum output current of 48 A (16 A per PSU), achieving up to 95% efficiency. Mechanical dimensions are 504.3 mm length × 446.3 mm width × 43.7 mm height with a weight of 4728 g, and the unit meets industrial safety standards including UL/CSA/EN/IEC 62368-1 certification with RoHS 3 compliance. For large-scale deployments, stacking 12 shelves in a 16U cabinet provides 144 kW total power, making it ideal for commercial grow operations requiring reliable, maintainable centralized power distribution.
