The 6U 36kW Integrated ET48600 DC Rack Power System represents a compact, carrier-grade DC power conversion solution tailored for telecommunications central offices, mid-to-large scale data centers, and industrial settings requiring uninterrupted DC power. Operating from a single-phase 220V AC without a built-in circuit breaker, it employs rear copper busbars for wiring and provides fine-adjustable DC output ranging from –43V to –58V, with a nominal setting of –53.5V. With a peak capacity of 36kW, the system consistently achieves conversion efficiencies exceeding 96% across a broad load spectrum—lowering both electricity costs and cooling demands.

Built for high availability and ease of service, the system leverages a fully modular layout that accommodates up to twelve 3000W rectifier modules configured in N+1 or higher redundancy schemes. Each module is hot-swappable, weighs less than 2kg, and incorporates forced-air cooling with active power factor correction (≥0.99) and low total harmonic distortion (THDi ≤5%), ensuring grid-friendly performance and clean DC output. The complete assembly is contained within a 6U chassis designed for seamless integration into standard 19-inch racks. Front-access hot-swap capability simplifies field maintenance, while rear copper busbars ensure low-resistance, high-current connectivity. With an IP20-rated enclosure, the system offers robust protection against incidental contact and debris ingress.

Power distribution is strategically governed by an integrated DC panel featuring both LLVD and BLVD capabilities, enabling intelligent load shedding and maximizing battery backup duration during mains outages. A sophisticated system controller allows comprehensive supervision and configuration, supported by 3 AI, 8 DI, 4 E-DI, 8 DO, and 8 E-DO ports, all fully user-programmable. Remote management is enabled via RS232, RS485, and SNMP interfaces, offering full oversight of alarms, performance metrics, and rectifier behavior. Local interaction is equally intuitive, with a front-panel LCD providing real-time system visibility and parameter adjustments—no extra tools required.

Designed to excel in demanding environmental conditions, the ET48600 operates reliably across ambient temperatures from –40°C to +65°C and humidity levels between 5% and 95% (non-condensing). It delivers rated power with no derating up to 3,000 meters above sea level. By integrating modular scalability, adaptive load management, and rugged construction, the ET48600 presents a forward-looking DC power platform for mission-critical environments where downtime imposes serious operational and financial impact.
