Read MoreThe Premium CRS-1000 Series DC/DC Converter is a high-efficiency power solution engineered for industrial and railway applications. Delivering up to 1000W of continuous power, it offers superior performance and reliability for critical systems operating in demanding environments.
Key features include high input-output isolation, adjustable output voltage, and remote sensing for precision power delivery. Designed according to EN50155 and EN45545-2 standards, the CRS-1000 is ideal for railway and industrial use. Its advanced protections, including overload, reverse polarity, and input under-voltage, ensure safe and consistent operation. With an efficiency of up to 94%, the CRS-1000 minimises energy loss while maximising operational performance.
The CRS-1000 supports multiple cooling options, including natural convection, fan cooling, and conduction cooling, to adapt to various applications. Operating efficiently within a wide temperature range (-40°C to 55°C at full load), it is built to withstand extreme conditions. The rugged design and a long lifespan of up to 350,000 hours make it a reliable choice for mission-critical power systems.
The Premium CRS-1000 Series DC/DC Converter is the ultimate solution for industries seeking dependable, efficient, and adaptable power management systems.
