The DPS 4000 Indoor Power System is a modular distributed power solution designed for mission-critical environments like data centers. It integrates lithium-ion battery backup with direct AC/DC conversion, eliminating centralized UPS units. Operating at 94% efficiency, it supports hybrid configurations (e.g., grid + DC lithium backup) and delivers localized power redundancy to individual server racks. During grid failures, its lithium batteries provide 480V DC power within 2ms, minimizing downtime risks while reducing energy losses by 30% compared to traditional systems.

How does the DPS 4000 achieve higher efficiency?
By bypassing inverter stages and using high-voltage DC distribution, the DPS 4000 cuts energy conversion losses. Unlike legacy UPS systems that require AC-DC-AC conversion, it directly routes grid power to servers through passive filtering. Pro Tip: Pair it with LiFePO4 batteries for 80% capacity retention after 4,000 cycles – critical for 24/7 operations.
Traditional UPS systems waste 12-15% energy through double conversion, but the DPS 4000’s direct coupling architecture maintains 94-96% operational efficiency. For example, a 10kW rack using this system saves ~1,400 kWh annually versus conventional setups. Transitional phases like grid-to-battery switching occur in <2ms via IGBT switches, preventing voltage sags. However, what happens if lithium cells degrade unevenly? Advanced BMS protocols actively balance cell voltages within 10mV tolerance, ensuring stable performance.
What makes the DPS 4000 suitable for modular data centers?
Its per-rack scalability allows incremental power upgrades without overhauling infrastructure. Each 3U module supports 8kW loads, enabling precise capacity alignment with IT growth. A 40-server rack typically uses 4-5 modules with N+1 redundancy.
Traditional centralized UPS requires oversized capacity planning, but the DPS 4000’s distributed topology lets operators add power units per rack. For instance, cloud providers can deploy 50 racks initially with 3 modules each, then expand as demand increases. The system’s CAN bus communication enables real-time load monitoring across 500+ modules. Practically speaking, this eliminates single points of failure – a failed module only affects its assigned rack. But how does heat management compare? With 97% efficiency at full load, each module generates just 240W of waste heat versus 600W+ for equivalent UPS units, reducing cooling costs by 18%.
