HFC150-W/G

HFC150‑W/G DC/DC Converters – Reliable Power Supply for Railway and Demanding Industrial Applications

The HFC150‑W/G DC/DC converters are specifically designed for applications that require the highest levels of reliability, robustness, and flexibility. With an exceptionally wide input voltage range from 14.4 V to 154 V, they can be used in virtually all international railway onboard power systems. This allows a single device to cover all common voltage standards—24 V, 36 V, 72 V, and 110 V—including the ±40% tolerance range required by EN 50155. This versatility makes the converters an ideal solution for operators and manufacturers seeking to standardize their systems while reducing overall complexity.

Another key advantage is the integrated hold‑up capability, which ensures a 10‑millisecond interruption ride‑through across the entire temperature and input voltage range at full load. This guarantees stable power delivery even under demanding operating conditions. The converters also offer a high efficiency of up to 93%, enabling effective energy utilization. The full output power of 150 watts is available across the entire temperature range from –40 °C to +85 °C according to OT4 ST1 without derating, further emphasizing their suitability for extreme environments.

The devices include comprehensive protection mechanisms such as integrated overtemperature and overvoltage protection. They are both no‑load safe and permanently short‑circuit proof, significantly simplifying system integration and increasing operational safety. Designed for chassis mounting, the robust IP20 housing ensures efficient heat dissipation, while the conformal‑coated electronics enable reliable operation in harsh environments. An open‑frame version is also available for applications requiring alternative integration options.

Compliance with EN 50155 and EN 50121‑3‑2 confirms the suitability of the HFC150‑W/G series for railway applications. With an isolation voltage of 3 kV between input and output, and PCB materials tested according to EN 45545‑2, the converters meet the highest safety and fire protection requirements. This makes them a reliable choice for applications where fail‑safety and standards compliance are essential.

Weighing only 700 grams, the converters are compact and highly versatile. They are available as single‑output versions with 24 V or 48 V, as well as dual‑output versions with bipolar ±15 V or ±24 V. This makes them suitable not only for railway systems but also for demanding industrial environments such as material‑handling vehicles or mobile machinery, where robust and efficient power solutions are required.
