📌 UPS ➡️ The Guardian of Critical Equipment

UPS (Uninterruptible Power Supply) provides immediate and stable power during mains power outages or abnormalities. Its core value lies in:

  • Uninterrupted Power Supply: Instantly switches to battery power during power outages, ensuring continuous equipment operation.
  • Power Purification: Filters out grid fluctuations, surges, and noise, outputting clean power.
  • Equipment Protection: Prevents data loss, file corruption, and hardware damage.

Given its importance, the electrical safety design of the UPS itself is crucial.

📌 Four Major Electrical Challenges Facing UPS

  • Surges and Overvoltage: Lightning strikes, grid fluctuations, inductive load switching.
  • Overcurrent and Short Circuit: Abnormal battery charging and discharging, load short circuits, inverter failure.
  • EMI and Harmonics: Internal high-frequency switching noise, grid harmonic interference.
  • Overheating and thermal runaway: Long-term high-load operation leads to severe battery overheating.
