This is a DC-DC converter that supports a redundant modular system. It features built-in dual rail DC input contacts and a single output, making it suitable for a wide range of applications within a broad temperature range of -40°C to +80°C. 【 What is Redundant Modular? 】 Redundancy in a system is not a negative concept. By using multiple units in parallel, if an issue arises that renders one unit inoperable, another can start up as a backup power source, maintaining the safety of the system. It serves as a backup power source to enhance the overall reliability of system operation. 【 Features 】 - Wide temperature range from -40°C to +80°C - Usable in harsh environments - Built-in dual channel DC - OK signal and alarm relay contacts - Supports 1+1 and N+1 redundant systems - Isolated design for primary and secondary sides - Protection: overload protection, short circuit protection - Certifications: UL / EAC / CE / CB / UKCA - Long-term warranty of 3 years
