Ⅰ. Power Stability Challenges in Data Centers

1. Critical Equipment Reliability Demands

• Server clusters and storage arrays require voltage fluctuations ≤±1% to avoid data transmission errors and equipment downtime.
• Network core switches are sensitive to voltage sags, with momentary fluctuations potentially causing routing table loss and service interruptions.
• Precision air conditioners and cooling equipment behind UPS systems may shut down due to unstable voltage, leading to a surge in PUE values.

2. High-Density Load Management Dilemmas

• When the power density per cabinet exceeds 20kW, traditional stabilizers’ delayed response can trigger chain power outages.
• Distributed power access in modular data centers results in grid total harmonic distortion (THD) exceeding 8%.
• In aged grid environments, voltage deviations exceeding ±10% occur frequently, threatening the lifespan of IT equipment.

3. Green Data Center Compliance Pressures

• Under carbon neutrality goals, stabilizer efficiency must be ≥95% to reduce PUE values.
• High-density deployment scenarios require small-sized, efficient heat dissipation equipment to avoid additional air conditioning loads.
