SYNOPSIS:
|
|
| ENERGY SAVING LAMP CONTROLLER
helps in reducing energy consumption by reducing the applied voltage
without a proportionate reduction in the illumination level. In large
scale industries, the three phase voltage is maintained at 415 Volts as
per requirement. this means that the voltage across phase and neutral
will be 239 Volts. This is far above the rated voltage of the lamps.
Lot of energy is wasted as the corresponding benefit in terms of
illumination is not obtained. Life of the lamps also get reduced. The
ESLC can be used to reduce the voltage applied to the lamps to anywhere
between the supply voltage and 180 volts TO SAVE ENERGY AND EXTEND LIFE
OF THE LAMPS. |
 |
These are suitable for fluorescent
and other types of lamps including
incandescent, mercury vapour, metal halide and quartz. The device
enables the user to adjust level of savings upto 50%. The first 10%
saving can be realized without any perceptible drop in illumination
level. The ESLC controls entire circuits of lighting from the lighting
distribution board and is a superior alternative to switching off
lamps, on a selective basis to save energy. Further delamping results
in uneven distribution of lighting. With the ESLC it is possible to
reduce the energy consumption without substantially reducing the level
of illumination and obtain even distribution. It is easy to install.

|
|
|
OPTIONAL:
|
|
|
Facility to control
the output of the ESLC based on the ambient light i.e., when the
ambient light is high, the output of the ESLC is automatically reduced
to obtain the best energy saving possible without any reduction in the
level of illumination.

|
|
|
|
|
Energy Saving 678.9 - 606.1 W =
72.8 W
In percentage : 72.8/678.9 * 100 = 10.7% |

|
|
|
|
Energy Saving 678.9 - 522.0 W =
156.9 W
In percentage : 156.9/678.9
* 100 = 23.1% |
|

Conclusions:
|
|
|
a) Energy saving in
auto mode (automatic adjustment of voltage based an ambient light) 10.7%
b) Energy saving when output voltage is manually set at 180 : 23.1%
Performance
Test at a Textile Unit given by the Customer :
We wish to inform you that we have tested your Energy Saver Light
Controller (make Vijay Energy Products, Madras) with 20 Nos. 80 Watts Tube
Light Fitting for a week and the test results are as
follows :
|
|
Average Energy consumed/hr.
Without the Energy Saver
|
2.02 units
|
|
Average Energy consumed/hr. With
the Energy Saver
|
1.74 units
|
|
Saving
|
0.28 unit
|
|
|
|
|
|
Assuming the cost of
energy is Rs.3/- per unit, there is a saving of Rs.20/- per day or
Rs.7258/- per year.
