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

The RSDH Series is an isolated DC-DC converter that supports an ultra-wide input range of DC 250V to DC 1,500V. It provides a stable DC power supply to control equipment in high-voltage DC environments such as solar power generation systems, energy storage systems, and EV charging facilities. Additionally, it is coated internally, making it resistant to dust and dirt, ensuring reliable use even in long-term operations.
