Vox Power | VCCR300 Single Output 300W DC/DC Conduction Cooled PSU

The VCCR300 conduction cooled power supply is a robust and highly reliable DC/DC converter delivering up to 300 Watts in a compact 7.43” x 4.6” x 1” low profile package, ensuring easy integration in virtually any orientation, providing system designers great flexibility and space saving advantages.  With a calculated MTBF exceeding 2 million hours, the VCCR300 series offers long term reliability and the ultimate power solutions for demanding applications in rugged and high vibration environments. 

The series provides a broad DC input voltage range, catering to standard 48V, 72V, 96V, and 110V railway battery requirements as outlined in EN50155. Its high-efficiency design minimises heat output, yielding a wide operating temperature range of -40°C to +70°C (+85°C for 10 minutes) with minimal cooling requirement. It offers standard output voltages of 12V, 24V, 36V, and 48V, all of which also feature a wide adjustment range of 90% to 125%. 

Higher power solutions of 300 Watts, 600 Watts, 900 Watts and beyond can be achieved by using the onboard droop current share function, which allows end users to scale up or down depending on their power requirements while sharing the power load equally between each 300W product.

Internal fusing and full power 10ms holdup are included as standard and a remote shutdown signal can place the unit in a low power standby mode and the input undervoltage level can be programmed to meet specific application requirements. State-of-the-art conformal coating technology enhances reliability and performance by safeguarding against environmental factors and providing additional mechanical support.

The series meets the requirements of the latest railway standards (EN50155), MIL-STD-810G (Shock & Vibration) and is approved to the latest industrial safety standards (IEC/UL62368-1 3RD Edition). EMC emissions and immunity exceed the requirements of EN50121-3-2, EN55035 and EN55032 class B.
