Product Summary
The EX-3 is a professional high power constant voltage DMX Driver designed to control large num-
bers of LED downlights or very long lengths of LED tape. The driver has built-in diagnostics that are
indicated by three tricolor LEDs on the front panel.

EX-3 DMX Driver
Patch Cable RJ-45 2m
Operating Environment
The unit is intended for indoor use only.
The unit will operate satisfactorily in an ambient temperature range of 0oc to 35oc. If this is exceed-
ed, the unit will shut down to a safe operating level.
Absolute Maximum Ratings
Input Voltage : 24V
Output Current: 6A per channel (internally limited by shutdown)
Output Power: 570W at 24v, 288W at 12v

Glossary
Base Address: The address, set by front panel DIP Switch that the unit decodes and sends to the out-
put terminal as a PWM signal.
Dimmer: One discretely controlled device or parameter of a device out of 512 possible in the DMX512
protocol. Also referred to as “Address”, “DMX Channel” or “Output Channel”
DMX: 512 addresses or slots' worth of control information as conveyed by DMX512 protocol. A light-
ing system may have more than 512 discrete things to control, so multiple universes may be
required.
PWM: Pulse Width Modulation. The preferred method of dimming LEDs.
SELV: Safety Extra-Low Voltage.
Features
 Complies with the essential requirements of EN 61347-1 General and safety requirements for
lamp control gear and EN 61347-2-13 Particular requirements for electronic control gear for LED mod-
ules.
 Decodes 4 channels of DMX
 2 x RJ45 DMX Connections, DMX in and DMX out
 DMX Out signal is buffered for glitchless downstream operation
 6 pin output to LEDs
 Status LEDs that indicate: DMX Active / Inactive
Overtemperature / Overcurrent
Overvoltage / Undervoltage
 Override switch inputs allow operation at 50% or 100% output in the event of a DMX
controller failure
 MOSFET output devices that offer high reliability, long service life and exceptional re-
sistance to static discharges
 Maybe left infinitely connected to open and short circuits
 Automatic shutdown in the event of overtemperature , overvoltage or overcurrent

Front Panel Layout
Wiring The Lights and Power Supply
The LED driver is designed to run 12 or 24v LEDs. They connect directly to the green output
connector as follows:

Setting the Base Address
The base address is set by the DIP switch as follows:
Flipping the switch UP adds the number indicated to the base address. Thus, if the switches
marked 1 and 8 were UP, the base address would be 9.
The base address is selectable between 1 and 510.
If no DIP switch is selected the DMX driver assumes the address 1.
Connecting the DMX
The pinouts are as follows for both DMX in and DMX out
When the DMX is connected and active the system status LED will go from flashing to solid green.

Switch Override Inputs
In normal operation, this function is not required. However, in exceptional circumstances, for ex-
ample a failure of the main DMX signal or a requirement to drive more than 3 LEDs, this is a use-
ful feature.
The additional modes are invoked by shorting-out the centre terminal to one or both of the other
screw terminals with a piece of wire, as shown above. The modes are described below:-
Mode 1: This is the default mode and decodes 4 channels of DMX at 12v
Mode 2: This mode allows the unit to accept an input greater than 12V. The maximum input volt-
age is 24V DC.
Mode 3: In the event that the DMX controller fails to output a signal, or there is a cable break,
this is a standalone mode that drives the LEDs at 50% output. The unit ignores the DMX input
signal.
Mode 4: In the event that the DMX controller fails to output a signal, or there is a cable break, this
is a standalone mode that drives the LEDs at 100% output. The unit ignores the DMX input signal.

Troubleshooting
The system status LEDs give a useful indication of what is going on. The ideal indication is 3
steady green LEDs. The indications are as follows:
System Status
Solid green - DMX active, all OK
Flashing green - system OK but no DMX received
Solid orange - low voltage
Flashing red - overvoltage, output limited to 25% (Mode 1 only)
MOSFET status
Solid green - OK
Solid orange - transistors running within safe limits
Flashing red - overtemperature, output limited to 25%
Ambient temperature
Solid green - OK
Solid orange - unit running within safe limits
Flashing red - overtemperature, output limited to 25%
