300W Single Output Conduction Cooled Power Supply.
The VCCR300 conduction cooled power series is a robust and highly reliable DC/DC power supply capable of delivering up to 300 Watts in a compact size measuring only 7.43 x 4.6 inches. Its unrivalled 1-inch low profile, ensures 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.
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.
