Install in a dry sheltered position
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 DMX signal. The constant voltage version
switches up to 5A per channel

Installation
Power
Connect the input voltage (between 12 & 24V) 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.
PWM Input
Connect a low side switched PWM source (such as the LDMX-PWM-3) to the PWM In pins. Connect
V+(1) to the positive side of the PWM (marked as V+ on the LDMX-PWM-3), then the 1, 2,& 3 pins to
the desired channels.
The 1, 2 & 3 pins can be connected together in order to drive up to 15A on a single PWM source.
The PWM inputs are optically isolated from the rest of the circuit.
LED Fitting
Wire the LED fittings(s) to the Output port of the LDR. The 1, 2 & 3 pins on the output are an exact
copy of the PWM input signal.
