VCCR Reviews & Product Details

The VCCR300 series by Vox Power is a robust, conduction-cooled DC/DC power supply delivering up to 300 Watts in a compact 7.43 x 4.6-inch footprint with a low 1-inch profile. Designed for demanding applications in rugged and high-vibration environments, it offers long-term reliability with a calculated MTBF exceeding 2 million hours. The series supports a broad DC input voltage range, accommodating standard 48V, 72V, 96V, and 110V railway battery requirements as outlined in EN50155. Its high-efficiency design minimizes heat output, allowing for a wide operating temperature range of -40°C to +70°C, with the capability to handle up to +85°C for 10 minutes. Standard output voltages include 12V, 24V, 36V, and 48V, each featuring a wide adjustment range of 90% to 125%. The onboard droop current share function enables scalable power solutions up to 900 Watts and beyond by equally sharing the power load between units. Additional features include internal fusing, full power 10ms holdup, remote shutdown signal for low power standby mode, programmable input undervoltage level, and state-of-the-art conformal coating for enhanced reliability. The VCCR300 series meets the latest railway standards , MIL-STD-810G , and is approved to the latest industrial safety standards .
