The DEP series industrial-grade modular intelligent Emergency Power Supply (EPS) is specifically designed for the characteristics of industrial power systems, catering to large industrial enterprises. It is primarily used for critical equipment and scenarios requiring highly reliable uninterrupted emergency power supply, such as emergency lighting, accident lighting, emergency pumps, industrial drives, and fire protection systems (including fire lifts, roller shutters, fans, water pumps, sprinkler pumps and supply pumps). This series of products is designed according to industrial-grade standards and features a “plug-and-play” modular design. Utilizing the inverter magnetic parallel patent technology independently developed by U.S. LDC, it achieves unlimited parallel redundant operation. With the optional power equipment lifecycle management system, it enables fault detection, automatic fault maintenance, and lifespan prediction. This series includes both three-phase input, single-phase output and three-phase input, three-phase output models.
