What this product is
What this product is
An ultra-dense DC subrack system integrating AC power distribution, three hot-swappable rectifier bays, one intelligent supervisory slot (SMU01C/SMU01B), and multi-channel DC distribution with battery and load breakers within a standardized 1U form factor (43.6mm height).
What problem it solves
Eliminates physical space limitations in 1U-reserved outdoor cabinets, safeguards systems against severe grid anomalies via wide voltage resilience, prevents lead-acid/lithium battery deep discharge using intelligent LVD, and simplifies remote management in unmanned sites.
Who and where it is for
5G/4G wireless base stations, access network central offices, optical transport nodes (FTTx/OLT), railway signaling/dispatch centers, and industrial automation control racks.
Core advantages
- Ultra-Compact 1U Density: Delivers 90A pure DC power within a 43.6mm height, preserving critical cabinet U-space
- High Energy Efficiency: Reaches ≥96% conversion efficiency with R4830G1 rectifiers, drastically lowering operational costs
- Extreme Voltage Adaptability: Operates stably between 85V AC and 300V AC; withstands up to 415V AC phase surges
- Two-Stage Low Voltage Disconnect: Configurable LLVD and BLVD thresholds to maximize uptime for primary mission-critical loads
