Isolated DC/DC converter RPM-450

step-upstep-downregulated

Product Overview The Neousys RPM-450 is a rugged buck-boost DC-DC converter that delivers a stable 13.8 V / 450 W output across a wide 9–32 V input range. Designed for 12 V / 24 V in-vehicle power systems and industrial applications, it smooths voltage fluctuations to ensure uninterrupted operation of high-power electronics. Even when input voltage drops to 9 V, the RPM-450 sustains a steady 13.8 V output, keeping back-end devices such as GPU computers running reliably without resets or power dropouts. Built for harsh environments, the RPM-450 operates fanlessly from −25 °C to +70 °C. Its compact form factor fits tight spaces, shortens cable runs, and reduces integration costs, while 94–96% efficiency minimizes self-heating and simplifies thermal management. The RPM-450 also features millisecond-level Undervoltage/Overvoltage Protection (UVP/OVP) with automatic recovery to safeguard back-end systems against unexpected voltage fluctuations. In addition, hardware Overcurrent/Short-Circuit Protection (OCP/SCP) prevents damage from overloads, and reverse-polarity protection guards against wiring errors. Front-panel LED indicators provide instant input/output status for quick diagnostics and reduced downtime. Stable power is the foundation of edge AI applications. The Neousys RPM-450 provides a reliable 13.8 V backbone for GPU computer systems—delivering consistent performance under variable input, reducing unexpected reboots, and extending system uptime.
