Easy conversion of all modern LED luminaires The ELP LD-CO emergency LED control gear allows maintained operation of high power LED modules or arrays, when utilizing the standard mains voltage LED control gear in-line with the emergency LED control gear. LD-CO Kits incorporate the appropriate LD-CO driver charger module, high temperature Nickel Cadmium (or Nickel Metal Hydride) battery, required connectors and charge indicator. In the event of a mains failure, an integral relay disconnects the LED lighting load from the mains control gear and then connects it to the emergency control gear which operates the LED module array at constant power providing a precise Emergency Ballast Lumen Factor throughout the entire duration of 3 hours. The various high power LED modules utilise different arrays of LEDs connected in series or a combination of series and parallel and there will be an ideal LD-CO kit to suit any of these. Each LD-CO module is configured for a maximum forward voltage and an optimum operating current. The LD-CO modules will operate any LED requiring a forward voltage below the maximum rating of the module. However, for best performance it is recommended that the LD-CO module with the rated forward voltage closest to the LED rating is selected. NB: Accurate selection of the best module for any given LED can easily be checked on the product selector at: www.elp.uk.com Note: For versions offering Self-Test or fully interoperable DALI control and reporting fuctions please refer to the LDpro range.
