EM emergency light drivers: the 2nd generation for linear and compact fluorescent lamps A generation change enables optimised stock keeping and greater design flexibility.
Dornbirn, July 17, 2014. The 2nd generation of the 3-part EM series features a new electrical design that enables the standard product portfolio to be halved and costs for stock keeping to be correspondingly reduced. The housing length has also been reduced from 280 mm to 230 mm, enabling the emergency light drivers to be more simply installed in linear and compact fluorescent lamps. All modules of the 2nd generation comply with current standards such as IEC 62034 and IEC 62386, ensuring representing safe investments in the future.
Luminaire manufacturers benefit from the electrical design as this provides new design options for smart, purist luminaire constructions. A further advantage of the new generation is that the emergency light operation duration (1 to 3 hours) can now be directly set via a jumper on the emergency light unit. In addition to the standard variants, emergency light units are also available with a special loading algorithm for NiMH batteries, increasing the life and reliability of these batteries.
As with the predecessor version, the 2nd generation also consists of the EM BASIC, EM SELFTEST and EM PRO product groups. The EM BASIC unit enables fundamental emergency light functions to be implemented and manually tested, while the EM SELFTEST group features integrated self-test functionality, the results of which are displayed via indicator LEDs. The EM PRO version enables tests for all devices to be individually set via DALI. Test results are displayed here with indicator LEDs and can also be centrally documented.
