Static Inverter Systems

The significant advantage of using a Static Inverter System for emergency lighting is that it allows the use of a wide range of normal functional or decorative mains luminaires as emergency fittings. The system eliminates the need for a separate low voltage system or
self-contained luminaire emergency lighting installation.

Our Static Inverter Systems are able to provide the following input and output configurations:

  • Single Phase Input : Single Phase Output

  • Three Phase Input : Single Phase Output

  • Three Phase Input : Three Phase Output

On Mains failure, the system converts DC power from the central battery to AC output.

Our systems allow the use of our modern energy efficient luminaires, while our on-line ‘NO BREAK’ inverter systems enable the use of high-pressure discharge lighting.


A totally integrated, energy efficient cost-effective and unobtrusive solution for all Emergency Lighting situations:-

  • Passive Standby
  • Active Standby
  • No-Break for ALL lighting loads including high pressure discharge
  • All systems can be configured 1:1, 3:1 or 3:3
  • Integration with our complementary products for Emergency Lighting

Our low cost flexible Passive Standby Static Inverter System is ideal for use with fluorescent and incandescent lighting sources. Traditional technology provides proven reliability with one of the lowest component counts in the industry. Low heat output, high
efficiency (typically greater than 95% AC-AC).
Conforms with all current relevant harmonised European standards.


“Active Standby” is our constantly running, off load, Static Inverter which can be monitored for function at all times — reassuring to know that the system will work when an emergency load is applied.


We manufacture a “No-Break” Emergency Lighting Static Inverter System that guarantees there will be no changeover switching of the supply to the load on mains failure. The load is totally unaffected by supply variation and is constantly fed with
stabilised, smoothed and conditioned power.
