Easy conversion of all modern LED luminaires

LD-CO emergency LED control gear allows maintained operation of high power LED modules or arrays, when utilising the standard mains voltage LED control gear in-line with the emergency LED control gear.

The LD-CO Kits incorporate the appropriate LD-CO driver/charger module, high temperature Nickel-Cadmium (or Nickel Metal Hybride) 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 module will operate any LED requiring a forward voltage below the maximum rating of the module. However, for the best performance it is recommended that the LD-CO module with the rated forward voltage closest to the LED rating is selected.

Note: For versions offering Self-Test or fully interoperable DALI control and reporting functions please refer to the LDpro range.

Selecting the correct LD module can be a tricky business so we’ve developed an app to help you. All you need to know is the forward voltage and forward current for your application. The app will tell you which modules are suitable (in some cases there will be more than one) and also what EBLF figure you can expect to see. CLICK HERE for our LD Product Selector.

It is very important to note that some of the LED module manufacturers specifically warn not to operate their products on reduced constant current supplies and the design of the LD-CO conversion equipment has taken this into account.
