Uninterruptible power supply systems are critical components of data center electrical infrastructure. They protect IT equipment from voltage fluctuations and provide instant power when utility service is interrupted.
However, UPS systems can only sustain operations for a limited period of time, typically a few minutes. During that window, backup generators start and assume the electrical load.
Generators can operate for extended periods as long as fuel is available, ensuring that the facility remains operational during prolonged outages. Designing these systems requires careful coordination of redundancy levels, fuel storage capacity, and maintenance requirements.
