Generally used in Emergency Lighting applications, a Static Inverter will maintain power to lighting for a period of 1 hour or 3 hours (depending on specification - as per EN 50171:2001).

BS EN 50171:2001 specifies the general requirements for Central Power Supply Systems (also referred to as Central Supply Systems) for use with essential saftey systems.

A Central Power Supply is used to power emergency escape lighting in the event of mains power failure, and may be suitable for use with other systems such as:

  • Fire Saftey (Extinguishing Systems, Lifts, Smoke Extraction)
  • Paging/Signalling Systems
  • Specialist Warning Systems (e.g. Carbon Monoxide Monitoring)

A UPS can be used to support these loads, however it will typically be a specially designed version to meet the requirements of EN 50171:2001.
A standard UPS will not meet this specification, and should not be used for life-saftey applications.
