Notes
•Install in a dry sheltered position
•Interior use only
•Ensure adequate ventilation
•Installation should only be performed by a qualified professional
•Install in accordance with all appropriate wiring standards
•Never connect a LED fitting to a driver that is powered. Doing so may result in damage to the LED.
•Always make sure the output voltage range and output current of the LED driver match the
requirements of the LED fitting. Failure to do so may result in damage both the driver and fitting.
Introduction
The LDR range provides a cost-effective means to expand a LED dimming system without the need for
extra protocol receivers, by simply repeating the input PWM signal. The constant voltage version switches
up to 15A, making it suitable for higher current fittings and strips.

Installation
1. Open Enclosure
To access the wiring terminals, remove the top plate by first removing the 4 screws securing it.
2. PWM Input
Connect a low side switched PWM source (such as a single channel from the LDMX-PWM-4) to the PWM In
pins. The PWM in pins are optically isolated from the rest of the circuit.
3. LED Fitting
Wire the LED fitting(s) to the output port of the LDR.
4. Power
Connect the input voltage to the Power +/- Pins. This is also the power to the LED fitting(s) as such it
should be selected to match the power requirements of the fitting.
5. Close Enclosure
Replace the top panel (making sure of correct orientation) and secure it with the 4 screws.
