LDM NFC

LED Module Emergency Control Gear

the ELP LDM-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 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.

Microprocessor enabled features

• The Near Field Communication (NFC) interface allows for 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.

• The indicator LED provides fault information. Unlike most other manual test modules the LDM uses microprocessor technology to display various fault codes on the indicator LED which mirror the DALI codes ELP already have in place.

• 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 10 years)

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.

LDM emergency control gear

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. For the appropriate battery, indicator LED etc.
