Power Systems International Adds a Spark of Intelligence to Emergency Lighting Systems

23 September 2010

Power Systems International Limited introduces an innovative range of Emergency Lighting Systems. The ELS D series of digitally controlled intelligent power systems are designed to provide a centralised source of power to supply dedicated light circuits for open offices, stairways or emergency exit routes in all kinds of public premises.


When the mains power fails, these emergency lighting systems send AC 230V backup power to four dedicated circuits of lighting fittings and exit signs in the premises making it possible to see the way to the emergency exit. The maximum load that the ELS D 1,500 system can support is 1,500VA.

The new ELS D product is microprocessor controlled featuring a LCD display that can monitor for problems with the lighting including if lamps have failed, if there is a load earth fault or if output fuses have blown*. This information is all communicated to the central power unit via each of the connected lighting power circuits without the need for any additional sensing wiring.

The LCD display also allows you to keep a check on the mains voltage, VA power factor, watts, DC amps, inverter voltage, and battery condition. In addition it offers LED status indications and LCD alarm indications, and the commissioning engineer can set up parameters via the front LCD panel.

The ELS D series has excellent green credentials; in quiescent mode the system consumes a small amount of energy, just enough to keep the integral battery fully charged.

In an emergency situation or when the mains power fails the ELS D system automatically reverts to its battery and will provide 1,500VA of power for up to three hours.

The ELS D systems conform to EN50171 and are designed to fit into the typical building risers. The boxes are shallow, only 325mm deep x 500mm wide, with heights ranging from 750mm to 1200mm depending on the VA capacity and the battery autonomy.

The ELS D products are designed and built in the UK with manufacturing time taking four weeks from order acceptance date.
