Description ELP LDM60HOD/K The ELP LDM DALI-2 NFC range of emergency LED control gear allows maintained operation of high-power LED modules, when used in conjunction with the standard mains voltage LED control gear. The control gear also provides an integrated DALI power supply for connection to other DALI devices, which can be optionally activated using a NFC programmer. The emergency control gear incorporates a module/charger and a high temperature Lithium Iron Phosphate battery. In the event of a mains failure an integral 2-pole 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 at an optimum light output for the rated duration. LDM60HOD/K Enabled Features • The Near Field Communication (NFC) interface allows for the optional activation of an integrated DALI power supply and also the downloading of diagnostics to assist in any site issues. • An App is available that can be downloaded onto a phone or tablet which can read stored operating parameters including information such operating hours, how many tests have been performed, module thermals , etc. This is a unique feature that highlights installation conditions and aids fault diagnostics. • The LED current in emergency mode is automatically adjusted for maximum light output and is constant for the entire rated duration. • Smart charging of the Lithium Iron Phosphate batteries which have protection circuit fitted including thermal sensing. NB: Lithium Iron Phosphate batteries offer long life (up to 8 years) • The LDM range is available with fully interoperable DALI control and reporting function and comes with an integrated DALI PSU. Automatic Self-Test is enabled when no DALI bus is connected. LDM60HOD/K Description It is important to note that some LED mains control gear should not be operated with an open circuit load, to overcome this problem when first powering up the LDM range features a live in/ live out relay which ensures the load is in place before the mains driver is powered up. In Self-test mode the function and duration tests will take place at randomized times. If required, duration testing can be programmed by turning the unswitched supply off and on 3 times in 10 seconds at the required time. Note the function test will occur weekly at the same time. To ensure the correct operation of each type of LED module the correct LDM equipment should be selected. The total forward operating voltages of the LED module / arrays connected should be used to determine the appropriate LDM control gear. As default, the integral DALI power supply will be disabled. Please see the order codes on the last page if you would like this to be enabled or for the appropriate battery, indicator LED etc. https://www.elp.uk.com/product/ldm-dali-2-nfc/
