18kW 3U Rack Mount Highly Compact DC Power System for Telecom Equipment

Overview of 18kW 3U Compact DC Power System

The 18kW 3U compact DC power system is a highly integrated telecom rectifier solution, purpose‑built for space‑constrained cabinet installations where every millimeter counts. By combining high‑density power conversion with miniature circuit breakers (MCBs) and a carefully optimized internal layout, the system occupies just 3U of 19‑inch rack space—saving at least 2U compared to conventional designs, and freeing up valuable room for additional transmission or switching equipment. Despite its slim footprint, the system delivers a full 18kW of DC output, accepting a 220VAC single‑phase input and converting it to a stable, noise‑filtered ‑48V DC rail that meets the stringent requirements of modern telecom and data communication loads. At the heart of the system are six 3000W hot‑swappable rectifier modules, configured in an N+1 redundant architecture that ensures continuous operation even in the event of a single module failure. Built to industrial-grade standards and equipped with forced‑air cooling, the system maintains thermal stability and full rated performance across a broad temperature range, making it equally suitable for controlled indoor environments and more demanding field deployments.

The 18kW 3U compact DC power system is orchestrated by the MC2600 controller—a new‑generation DC power management platform developed specifically for modern hybrid power architectures. At its core, the MC2600 employs an ARM 32‑bit Cortex‑M4 CPU as the primary processor, delivering robust real‑time performance with low power consumption. The controller presents a comprehensive suite of features through a clean, intuitive, and user‑friendly interface, making system configuration, monitoring, and troubleshooting accessible to operators of varying expertise. Beyond its core functionality, the MC2600 excels in advanced hybrid energy management—integrating and seamlessly coordinating diverse power sources including diesel generators, VRLA batteries, lithium‑ion batteries, and solar PV modules—ensuring optimal energy utilization, fuel savings, and uninterrupted power delivery across varying grid and environmental conditions.
