Vox Power Ltd has recently announced the launch of their new product, the VCCR300 Conduction Cooled Series of DC DC converters. Aimed at the demanding requirements of the railway industry, the innovative VCCR300 series will find homes in a wide variety of rugged and demanding environments. Let’s look in depth into what makes the VCCR300 stand out and why it’s causing such a buzz in the industry. 

The VCCR300: A Powerhouse in a Compact Package

The VCCR300 is not just any DC DC converter; it’s a slim, fan-less, rugged powerhouse capable of delivering a whopping 300 Watts of power. Its compact size, measuring only 7.43 x 4.6 inches with an incredibly low profile of just 1 inch, is a marvel of engineering. This makes it an ideal choice for applications where space is at a premium, such as in telecoms, street and trackside furniture, 5G applications, electrified moving equipment, and transportation devices. 

Designed for the Demanding Railway Industry

Vox Power has always had a ‘loud’ presence in the power supply industry, and with the VCCR300, they’re not just talking the talk but also walking the walk. This PSU is specifically designed to meet the rigorous standards of the railway industry, complying with EN50155. It supports a broad DC input voltage range, catering to standard 48V, 72V, 96V, and 110V railway battery requirements.

Cool Under Pressure

One of the most impressive features of the VCCR300 is its high-efficiency design, which minimises heat output. This allows it to operate in a wide temperature range of -40°C to +70°C, and even up to +85°C for 10 minutes. This feature is crucial for applications in harsh environments where reliability is key.

Flexibility and Reliability

The VCCR300 offers standard output voltages of 12V, 24V, 36V, and 48V, all with a wide adjustment range of 90% to 125%. This flexibility ensures easy integration and versatility for customers. Additionally, higher power solutions of 300 Watts, 600 Watts, 900 Watts, and beyond can be achieved using the onboard droop current share function. This allows users to scale their power requirements up or down while sharing the power load equally between each 300W unit.

Safety and Standards

Safety is paramount, and the VCCR300 doesn’t disappoint. It includes internal fusing and full power holdup for 10mS as standard. 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. The unit meets the latest railway standards (EN50155 / EN50121), MIL-STD-810G (Shock & Vibration), and is approved to the latest industrial safety standards (IEC/UL62368-1 3RD Edition).

Long-Term Reliability

The VCCR300 is not just a short-term solution. With a calculated MTBF (Mean Time Between Failures) exceeding 2 million hours, it offers long-term reliability. This is further enhanced by state-of-the-art conformal coating technology, which protects against environmental factors and provides additional mechanical support.
