    Hi ..

    Wats up guys...?:)Ok Anyone have any idea about Cbus Energy controller modules...?how it works...?how to install it...?whether we can connect all phases together....?

    Energy Controllers

    Hi Matthew,

    The energy controllers (also referred to as auto-transformers) operate in the folllowing way.

    When the lights are first turned on, the auto-tranformer allows full voltage (240v in Australia) to the lights for approx 5 mins to allow the lamps to come up to temperature. Once this warm up period is complete, they reduce the supply voltage to the lamps by approx 20%.

    You need to consider the following though:

    They are normally fitted at the switchboard and cover the entire circuit.
    Energy controllers are ONLY suitable for flourescent lighting
    They come in three typical sizes - 10amp, 16amp, and 20amp.
    They need to be loaded to at least 80% of their rated load to afford satisfactory energy savings
    They are ONLY suitable for older, iron core ballasts. They will destroy electronic ballasts over time.
    They are generally not suitable for lighting circuits which also have emergency EXIT or supplimentary battery backed lighting. This is due to the charging circuits in the emergency lighting system not allowing complete charging on a reduced voltage supply.
    They can cause a noticable dimming of the lights. This is often noticed if you have several, seperately switched rooms. As each room is switched on and off, the energy controller will drop in and out of economy mode, causing the lights to brighten and dim.

    There are other options you should consider.
    Most lighting systems are over designed, and provide far more light than necessary. This in turn, burns more power.
    If the existing light fittings are old, and becoming a maintainence issue, consider replacing them with a newer, more efficent type - 28W T5 instead of 36w T8. In a twin lamp fitting, with iron core ballasts, this will equate to an energy saving of approx 36w per fitting.
    If you have access to the kw/2 reflector technology, you may be able to reduce your lighting from 2 x 36w lamps per fitting, to a single lamp fitting providing similar lighting levels. This can provide even greater savings by reducing the load of the fitting from approx 92w per fitting, to a very efficient 37w per fitting, giving an energy saving of some 55w per fitting.
    I have successfully completed several hundred lighting upgrades using the kw/2 lighting reflector technology with average energy saving of in excess of 20% based on lighting loads alone.
