Hamburg, 20 September 2016. At the Security 2016 trade fair in Essen, Pfannenberg presents the new Quadro-LED-Hi multifunctional light, the successor to the tried and tested Quadro-LED Flex. The Quadro-LED-Hi is used for the visual signaling of hazardous situations and to indicate the status or fill level of machines and systems. Possible areas of application include the operation of industrial machines and systems, building safety and controlling traffic on factory premises. The optical signals of the lights are created with LEDs with a high level of luminous efficacy. Thanks to robust mechanical construction and categorisation in high protection classes (IP 66, IP 67 and IK08), the Quadro-LED-Hi is suitable for indoor and outdoor use. Modular in design and multifunctional, they offer manufacturing companies, industrial installation and service firms, mechanical and systems engineering companies and the producers of lifting equipment and their service departments a cost-efficient, versatile and powerful signaling solution.
"The Quadro-LED-Hi has everything an industrial light needs: not only high light intensity but also wide coverage volume thanks to its well-thought-out design. Furthermore, it is extremely robust. Neither aggressive environmental conditions nor driving rain nor condensation can impair its performance. With many functions and combination options, industrial companies can cover a wide range of applications with one flexible lighting solution which can be adapted to their requirements," says Carsten Hippler, Product Sales Manager Signaling at Pfannenberg.
Powerful signaling
The luminosity of the Quadro-LED-Hi can be adjusted up to 75 cd. However, luminosity is not a sufficient measure of the effectiveness of a signaling device. The actual coverage volume under real environmental conditions is much more decisive and this has been shown for the first time with Pfannenberg's practical demonstration method 3D Coverage. This takes account of factors such as the type of alert and the positioning of the device. This method indicates that, used with a clear cover, the coverage volume of the Quadro-LED-Hi is as follows (width/height/depth): Information applications – 49.5 m x 47.5 m x 36 m; warning applications - 22 m x 21 m x 16 m and alerting applications 11 m x 10.5 m x 8 m.
Versatile in use
Users can adjust the operating modes of the LED light at any time within a flexible range of options: continuous, blinking frequencies at 1 Hz /2 Hz and flashing frequencies at 0.1Hz / 0.5 Hz / 0.75 Hz / 1 Hz /2 Hz. The Quadro-LED-Hi is even more versatile used with a multi-voltage power pack. There is a 24 V variant with a functional range of 11 V to 60 V (DC) and a 230 V variant with a functional range of 90 V to 253 V (AC) at 50/60 Hz. The lights are also equipped with an inrush current limiter. The Quadro-LED-Hi is designed for ambient temperatures ranging from –40 °C to +55 °C.
