New version of Ex fluorescent light fitting enables cost effective connection to central battery systems for emergency lighting
20/09/2011 Cooper Crouse-Hinds GmbH
COOPER Crouse-Hinds, a leading manufacturer of explosion-protected electrical equipment, has launched a new version of its popular eLLK 92 range of explosion-proof fluorescent light fittings. The new eLLK 92 DCA version has an integrated AC/DC module that enables connection to 220V central batteries. The module is integrated to the electronic ballast (EVG).Whilst many customers already use the CG-S range of Ex fluorescent light fittings from COOPER Crouse-Hinds, these units are considered high-end solutions, designed for the individual monitoring and programming of multiple light fittings within an emergency lighting installation. However, the eLLK 92 DCA is a more cost effective option for users that do not require individual monitoring, only circuit monitoring.
Gordon Low, Marketing Segment Manager at COOPER Crouse-Hinds UK Ltd comments: "The eLLK 92 DCA is another unique, innovative lighting product from COOPER Crouse-Hinds. By integrating the AC/DC module with the electronic ballast, our engineers were able to design and manufacture a very cost effective light fitting solution compared to solutions from other competing lighting suppliers."
The eLLK 92 DCA functions as a 2-lamp AC mains light fitting. However, in the event of a changeover to the DC supply via the battery, the eLLK 92 DCA switches to single lamp operation in its emergency lighting mode. In this way, the power consumption for the battery is halved, whilst at the same time, the luminance intensity is reduced.
The eLLK 92 DCA is protected to Category II 2G Ex d e IIC T4 in accordance with the ATEX Directive for use in potentially explosive gas atmospheres (Zones 1 and 2). The luminaire is also suitable for potentially explosive dust atmospheres (Zones 21 and 22) and is certified to Category II 2D Ex tD A21 IP66 T80 deg C in accordance with the ATEX Directive. The luminaire also complies with the latest equivalent IEC standards for gas and dust.
All eLLK 92 light fittings are made from high grade plastics which, as well as providing excellent mechanical properties, also offer high stability against many chemicals found in industrial plants. All the materials used in the eLLK 92 light fitting and its sealing system help to protect the unit from corrosion and contamination. The eLLK 92 has already been tried and tested in numerous chemical and offshore oil and gas installations worldwide.
