Robust technology for extreme
applications
The operation of explosion-protected light
fittings places high requirements on the
reliability and durability of the circuits being
used. In addition to temperature, moisture
and mechanical stress, mains contamination
or voltage peaks can affect the light
fittings. Here the EVGs specially developed
by CEAG provide safe protection against
harmful influences. Whereas conventional
industrial EVGs are designed for an ambient
temperature of the light fittings of up to
+ 30°C, the CEAG EVGs are designed for
an ambient temperature of + 50°C. The
large-scale printed wiring board layouts
ensure an even heat distribution, throughconnections
and encapsulation of sensitive
components provide mechanical protection.
A hermetically sealed enclosure provides
protection against undesirable substances
that could cause damage to the PCB.
All CEAG Light Fittings with EVG 97 have the
”green button“
Direct or alternating voltage?
Conventional ballasts only work with an
alternating voltage and can only be used
with group or central battery installations
under certain conditions. CEAG, as the
leading manufacturer of emergency lighting
installations, offers an explosion-protected
ballast that can be operated with alternating
and direct voltages.
Quality cannot be left to chance
Extensive testing and a highly automated
production process are necessary to
ensure a constant good quality. CEAG has
been manufacturing EVGs for 25 years and
EVG-Capsulation
2.8 CEAG SICHERHEITSTECHNIK GMBH
has the necessary know-how. In addition
to the routine verifications and tests carried
out on all apparatus, stress tests are carried
out on individual batches to ensure
safe findings with regard to component
specifications.
Computer-aided final inspections
The uncompromising safety of the explosion-protected
eLLK 92 light fittings is
maintained throughout the various production
stages and includes the final inspection.
Each light fitting is tested in detail by a
computer test program. All data relating to
the manufacture and safety is stored and
can still be called up years later. This is
where the CEAG quality assurance system,
that is certified to ISO 9001:2000, clearly
makes it mark.
