Cosel DCS DC-DC Converters

Cosel DCS DC-DC Converters offer a 1200W to 1404W output power range, up to 95% efficiency, and dimensions of 116.8mm x 12.7mm x 61mm. These converters provide constant current regulation, parallel operation, an optional built-in O-ring MOSFET, and various built-in protections, including overcurrent, overvoltage, and thermal protection. Flexible voltage settings are enabled due to the wide output voltage range, and the output voltage can be varied to near 0V. Cosel DCS DC-DC Converters are suitable for various distributed power systems.
