Das Einsparpotential durch Einsatz von LED in der
Beleuchtung beträgt ca. 40%
Project settings
20% of the power produced worldwide is used for
lighting purposes.
The possible savings through the convertion to
LED-technology is around 40%.
To supply and control (dimming) LED-lights, energy efficient devices
are required.
FG-ELEKTRONIK is manufacturer and supplier for energy efficient
LED- power supplies and
PWM- dimmer
for industrial and professional applications.

Minimizing the power consumption
of a ticket machine
A project example for energy - efficiency
12
24/7 operation in a variety of climates with different load
profiles determine ticket machines
Ticket machine characteristics
On a technical point of view ticket machines have the follwoing
charcteristics:
Different load profiles depending on the installation location
24/7 operation in a variety of climates
Several subsystems with different voltages (5 / 12 / 24V)
Distinct standby and partial load operation
Distinct peak load requirements
Use of control processors (EPC)
LAN or WAN connection to communicate with higher level systems
13
One of the key findings was that ticket machines consume
the majority of their energy use in standby mode
Analysis
Correlating frequency data and energy consumption for typical
processes showed:
More than 90% of the total energy consumption is used for
standby activities
Low frequented ticket machines reach a ratio of 1 to 100 for
operation energy to standby energy

All efforts towards increasing the efficiency have to focus on
the optimization of the standby mode
14
In the beginning of the project an increase in efficiency
of 30% seemed to be a real challenge for us
Our Targets
Improvement in efficiency at least of 30%
Ensured operation in any surrounding
No inconveniences for the customer, no loss of comfort
No cost increase for the manufacturer
A modular concept for more application flexibilty
15
Increasing ticket machine efficiency requires an integrated
approach
Our approach
Three ways to minimize power consumption in standby mode:
Substitution of electrical components by energy efficient alternative
modules if available on the procurement market
Power management
Switch off components not in use, and switch them on again
right in time
Peak load management
Installing a communication backbone and sensors to determine
the control parameters
High efficiency power supply unit

An increase of efficiency of about 70% is possible
Results
We started with a 500 W power supply and a
net power input of 140 W in the standby mode
In prototype I running now we reach an increase of efficiency of
more than 50 %
We use a high efficiency 240 W/10 A power supply to drive all
activities including battery charching an have a net power input of
about 65 W
The power boost capabilities of the power supply cover more 97% of
the peak load requirements.
The remaining rest is covered by using the built in battery
18
A turning point in energy policy will only be achieved if it
exhausts all possibilties for improving energy efficiency
Summary
We will not save the world only by building high efficiency power
supplies for ticket machines
In my opinion this project is kind of a message and the message is:
To think about efficient use of the available energy is at least as
important as building new power plants
In many everyday processes we can find considerable
potentials for energy saving
