DC/DC Converter for Railway Applications

News Editor

Autronic has launched the HFBC80-W/Ks DC/DC converter, a reliable and efficient solution for railway applications. This compact converter offers an ultra-wide input voltage range from 14.4 V to 154 V, making it suitable for a variety of on-board voltages used in railways. With a power output of 80 watts, the HFBC80-W/Ks can cover all international on-board voltages from 24 V to 110 V in a single device, making it a cost-effective and efficient option for railway applications.

The HFBC80-W/Ks DC/DC converter is designed to withstand harsh environments, with a full encapsulation that ensures vibrations, shocks, surge bursts are addressed, and it can be used in environments with high humid heat. The device's operating temperature ranges from -40°C to 85°C, making it suitable for use in extreme conditions. It is compliant with critical railway safety standards, including EN 50155 and EN 50121-3-2 (EMC), ensuring that it is a reliable and safe option for railway applications.

One of the key features of the HFBC80-W/Ks DC/DC converter is its high efficiency, which can reach up to 92%. It also has an integrated hold-up time of 10 ms (class S2), eliminating the need for external hold-up capacitors. The compact design of the device (113 x 46 x 35mm) allows for easy installation and its high efficiency reduces power losses, making it a cost-effective solution for railway applications.

The HFBC80-W/Ks DC/DC converter is equipped with inrush current limitation, overvoltage and overtemperature protection, and active reverse polarity protection, making it a safe and reliable option for railway applications. The device is open-circuit and continuously short-circuit proof, and can be connected in parallel with other modules, offering greater flexibility and scalability. The output voltage is also adjustable, providing greater customisation options.
