Four-Channel DMX PSU LED driver
According to the DMX-512 light communication protocol Excelitas provides DMX PSU to
drive the ACULED. The serial and digital DMX technology has been established as the most
important transmission standard in the stage and theater environment. The ACULED DMX
Power Supply product line is available as 350 mA and 700 mA four-channel drivers. The power
supply is equipped with integrated DMX interface and hence is used in professional light control
of LEDs, especially ACULED family products. The main application of the device is color mixing
of RGYB- or RBGW-ACULEDs, but any other kind of ACULED DYO combination can also be
operated easily.
The automatic color change in color mixing applications is controlled via an integrated device
with corresponding options. The device has four channels that can be activated separately by
the DMX-512 protocol. The start address can be adjusted by coding switches that are easily
accessible. With a maximum total output power of 30 W per channel for the 700 mA version or
15 W per channel for the 350 mA version, a constant current of 350 mA or 700 mA is available per
channel. Thus up to twelve ACULEDs can be operated with four different channels.
If a DMX signal is not available, the control of the LEDs can also be carried out by four external
potentiometers or by means of the integrated device. Several color cycles with different speed
are feasible. A master / slave function allows synchronous operation of several devices. The
LED outputs are short-circuit-proof. By means of additional temperature measuring input, the
temperature of the PCB of the LED can be controlled. The DMX PSU LED drivers are available
for 220 V input voltage.
Designer Kits
Excelitas offers various Designer Kits to easily run and test the different products of the
ACULED product family in your application. They are easy to use and ready-to-operate in a few
quick steps. Test and see how the Designer Kit can help you assess the functionality of the
ACULED products in your application. There are different versions available, but all have at
least a PSU, different ACULEDs mounted on through-looking PCBs for easy connection, heat
sinks and tools for assembly and mounting. Please contact Excelitas for more information on
the Designer Kits.
In table 7 the assignment between the ACULED PSU channels and the ACULED chip pads is
shown. Please refer to the manuals of the specific designer kit for detailed information on
connection and driving the ACULED with the equipment provided by the kit.
