UPS systems ensure greater reliability in critical infrastructures
Discover the requirements and standards for power supplies and DC UPS systems in critical infrastructures in this comprehensive article.
Specific requirements for power supplies and UPS systems in critical infrastructures concern reliability, robustness, and security: UPS systems ensure an uninterrupted power supply during power outages and enable an orderly shutdown of systems during prolonged outages.
Switchgear, transformers and uninterruptible power supplies (UPS) are key components of electrical infrastructure, each fulfilling a distinct role to ensure reliable and safe power distribution across various sectors, from commercial and industrial to residential and health care.
Currently, PULS offers two options for an uninterruptible power supply to the load in an emergency: both double-layer capacitors and lead-acid batteries can serve as energy storage in DC-UPS systems for industrial applications.
The minimum lifetime of DC-UPS and DIN rail power supplies is determined by the lifetime of electrolytic capacitors, which are the most critical element in the devices. Even a temperature increase of +10 °C in the power supply halves the lifetime of the capacitors.
