Description ELP LD64CO22D 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.
