Isolated DC-DC converters for the railway market RailQor DC-DC Converters
Artex Co., Ltd.
About This Product
■Product overview
The RailQor series is a synchronous rectifier that complies with the European railway standard EN50155 and is designed for railway products (LED indicators, audio amplifiers, safety monitoring devices, lighting, and communication systems) and achieves high efficiency even at low output. Next-generation DC-DC converters based on board-mounted, isolated, fixed switching frequency technology.
The 1/4 brick 25~50WMega series generates extremely little heat and can be used without derating without airflow or heat sink up to an ambient temperature of 85℃ inside the housing. Each converter comes with a case to protect it from the harsh environments found in many industrial applications (robots, displays, factory automation, power generation systems) and rail/transportation applications.
■Basic performance
