The Clipsal Energy Controller is designed to save energy consumed
by fluorescent luminaires. The unit operates in one of two modes,
Normal or Economy. In Normal mode, the standard supply voltage (240Vac/230Vac/220Vac)
is applied to the load. After a short time to allow lamps to strike
and warm up, the Energy Controller enters Economy mode and the voltage
applied to the lamps is reduced.
When running in Economy mode, the voltage is decreased by approximately
15% of the supply, and energy consumption by fluorescent lighting
is reduced by up to 30%.
The Clipsal Energy Controller has a patented soft switching, zero
crossover system with both voltage and current sensing; this combination
avoids "brownouts" in a falling voltage situation. It also
senses when other luminaires are switched 'on', returning to Normal
mode to allow them to strike and warm up before returning to Economy
mode.
Fluorescent luminaires are normally operated within the standard utility
supply voltage. The nominal supply voltage is only required to allow
the luminaires to strike. Thereafter, the operating voltage can be
reduced with only a small reduction in light output.

When a bank of luminaires is turned on, the Energy Controller holds
the voltage at nominal for a preset time and then returns to economy
mode.
When additional luminaires in a line are turned on, the Energy Controller
senses the change in current and switches back to mains voltage,
the timer restarts to allow the newly switched lamps to warm-up.
This small change in light level during the change in voltage is
difficult to detect with the human eye.
The Energy Controller is designed to retrofit into existing installations;
no modification is required to existing luminaires. Interruption
to lighting and downtime can usually be limited to a matter of minutes.
Clipsal Energy Controllers are compatible with iron core type fluorescent
ballasts. Electronic ballasts must not be used. They may be used
in conjunction with any type of fluorescent starters used in switch-start
fluorescent circuits. For example, electronic or bi-metallic/glow
type starters can be used.

Recent developments in climate change in the UK, has meant that Tony
Blair has had to review his targets for cutting carbon emissions levels.
The most recent data for carbon emissions reduction shows that the levels
the UK signed up to at the recent world summit of economic leaders will
not be achieved. With this in mind the government set up a body called
The
Carbon Trust to make people aware of their responsibilities
in this area, and also to target funding for specific products and projects
which will help the government achieve its stated targets.
The Carbon Trust has deemed that The CBUS energy controller which we
install meets the requirements for helping to reduce carbon emissions.
It does this by reducing the energy consumption of fluorescent lighting
without people noticing a difference in lighting levels. Based over a
year it reduces energy consumption and the consumers electricity bill
by up to 30%. Less energy consumed means less power needing to be generated
hence less carbon emissions being emiited into the atmosphere. To help
companies achieve the savings The
Carbon Trust is offering interest free loans to any business
wishing to have the controllers installed into their buildings.
With this in mind NDR Systems in conjunction with Cablelines,
the national distributor of CBUS are trying to inform councils at a local
level of this potentially ground breaking development through seminars and
direct contact with local businesses.
