The company’s solutions are specifically designed to be the primary insulation barriers for railway DC power architecture. All converters are also equipped with standard DIP, 2”x1”, and quarter brick packaging. MINMAX converters are highly reliable and ideal for use in railway applications such as backup power systems, train operation monitors, gate controllers, and traction inverters.

DC-DC power converters for railway applications

MINMAX’s certified DC-DC converters are available for various DC battery bus voltages and feature tight regulation for a range of output voltages. In accordance with EN 50155:2017 certification requirements, the railway certified DC-DC converters conform to railway DC input-voltage ranges and transient/variation requirements, including the voltage isolation, test vibration, and shock/bump requirements in EN 61373.

An advanced circuit topology provides a very high efficiency of up to 93%, which allows a base plate temperature of up to 105°C and a very high I/O isolation of up to 3,000V AC, with reinforced insulation. Further features include overload, overvoltage, and short-circuit protection, as well as remote on/off controls, output trim, and output sense. For fire protection testing, the converters meet EN 45545-2 standards to ensure system safety.

High-performance power conversion solutions

MINMAX provides fast turnaround times and high quality, along with efficient service and technical support. The company also prides itself on supplying customers with products and effective service in a timely manner. Adhering to the best quality standards has also helped MINMAX to become a preferred business partner in the rail industry.

The company also works hard to reduce any negative environmental impacts.
