CHS700

The CHS700 series DC-DC converters from Cosel are high-efficiency, high-power bus converters designed for industrial and electronic applications requiring up to 702W of output power. This series is available with a 12V output delivering up to 58.5A, making it ideal for demanding systems. The CHS700 operates with an input voltage range of 36V to 76V DC, providing flexibility for various power systems.

Designed for efficiency, the CHS700 series achieves up to 96% efficiency, minimizing energy loss and optimizing performance. The converter features remote ON/OFF functionality with negative logic (L: ON, H: OFF), remote sensing, and adjustable output voltage via an external resistor, allowing precise control of power output for specific application requirements.

To ensure safe and reliable operation, the CHS700 series includes overcurrent protection, overvoltage protection with auto restart, and a low ripple and noise design to ensure smooth and stable power output. The series also supports multiple cooling methods—convection, forced air, and conduction—allowing for enhanced thermal management in different environments.

Built to handle harsh conditions, the CHS700 operates across a wide temperature range from -40°C to +85°C, at altitudes up to 5,000m. The series is designed to withstand high vibration and impact, making it durable for industrial use. The compact form factor, with dimensions as small as 58.4 x 10.5 x 36.8mm and weighing only 72g to 100g, allows for easy integration into space-constrained applications.

Certified to global safety standards including UL62368-1, C-UL, and EN62368-1, the CHS700 series is a robust and efficient solution for high-performance DC-DC conversion, suitable for power-critical systems in industrial and electronic applications.
