LIGHT + CURRENT
LED systems for industrial lighting and floodlighting
ACDC Dynamics is the sole distributor of the Italian designed
Gewiss product ranges in SouthernAfrica.We would like to intro-
duce you to the Smart [4] LED lighting range for industrial lighting
and floodlighting applications. Intelligent lighting provides the
ability to adapt to the environment. This can be achieved by se-
lecting the best solutions in terms of effectiveness and efficiency,
for any application and in any environment.
Smart [4] is the new lighting range by GEWISS that interprets
intelligence exactly from these points of view and provides ver-
satility and adaptability, thereby defining the
unique aspects of its identity and in doing
so, offering sustainable lighting. Another
unique point would be that Smart [4] offers
the most varied types of application and
in which lighting performance is a must.
Smart [4] can be a floodlight, high bay or
ceiling light as needed, offering different
photometry’s depending on the different applications.The benefit of
the new luminaires guarantees optimal lighting performance in any
application, from industrial to sports environments, indoor or outdoor.
That is not all. The horizontal and vertical modularity of the new
product is combined with the ease of installation and maintenance,
with the use of ‘green’ materials and with the unmistakable style of
an Italian design. Energy efficiency, light quality and an immediate
return on investment, ease of use and speed of implementation: these
are the characteristics that make Smart [4] a truly intelligent product.
Benefits of Smart [4] include:
• Performance: Smart [4] was developed by the GEWISS research
centres to reduce the Total Life Cycle Cost and therefore make it
affordable to replace lighting systems.
• Energy consumption: Using Smart [4] products instead of tra-
ditional light sources yields energy savings of up to 60 %, in
comparison to other systems and up to 80 % in comparison to
obsolete or poorly maintained systems.
• Configuration: Various methods and configurations ensure a flex-
ible solution for any application
• Installation: The entire Smart [4] product range was designed and
developed tomake it easy to install and retrofit on existing devices
and in obsolete lighting systems.
ACDC prides itself in providing only the highest quality product ranges.

New to the biogas generator market
With the build of our first biogas fuelled
generator, Diesel Electric Services has now
entered the biogas market, one that is sure
to grow as we look for alternative sources of
energy. In this case, the source of the energy
is waste material from a chicken abattoir.
The gas generated from the digestion of this
material has sufficient quantities of methane
to generate power. The unit supplied can
export 150 kWof electrical power.The prime
mover is a 6 cylinder, spark ignited recipro-
cating piston engine with turbocharging and
intercooling.To gain as much use out of the
biogas as possible, 230 kW of heat is recov-
ered from the engine jacket, oil cooler and
exhaust gas.This heat is used to heat water
from ambient conditions to 80 °C which is
then used at various places in the process.
The generator will operate on a continuous,
24/7/ 365 basis, parallel to mains and offset
the load from the rest of the plant. In the
event of a power failure, the generator will
supply power to the auxiliary systems of
the biogas plant to ensure there is no loss
in production of the biogas. As is often the
case with new technologies, several ‘teeth-
ing’ problems were encountered once the
build was complete. These were overcome
through extensive in-house testing, made
possible by the installation of a permanent
natural gas line earlier in the year. The end
result is a product delivered to site that only
requires minor adjustment of settings to ac-
commodate the biogas fuel.

LEM, Geneva, Switzerland has released a new
range of current transducers designated the HO
series.The HO series is a breakthrough in the trade-
off between performance, cost, size and mounting
versatility. The six families cover nominal current
ranges from 2,67 A to 250 A. PCB, through-hole,
surface-mount or multiple panel mounting ver-
sions. Apertures, or integrated primary conductors,
are also available.The LEM HO series is based on
new LEM ASIC (Application Specific Integrated
Circuit) which brings open-loop transducer perfor-
mance closer to closed-loop types, providing better
control and higher accuracy at a significantly lower
price. Important features include:
Single +5 V or +3,3 V power supply Fast response time from 2,5 to 3,5 μs
Up to 8 mm creepage and clearance Over-drivable reference voltage
Half the offset and gain drifts of previous generations Fault report function
Overcurrent detection on a dedicated connection Versatile panel mounting version (3 ways).
-40 to 105°C operation
