3.1 Pin Description
Vin
Supply voltage input. Apply a DC voltage of 7V to
32V here.
GND
Ground reference.
DMX+/DMX-
RS485 DMX port, connect direct to the DMX bus.
Close jumper for bus termination.
I2C
SDA, SCL lines of the I2C interface. Use only
SDA, SCL and Gnd to connect to any self supplied
controller or computer.
+5V is a power output from LED-Warrior04 that is
generated from Vin. +5V can supply power to add
on modules like the wireless module. Do not
connect an external power supply here!
DA
The IEC62386 physical bus interface module can
be placed on this header
Ch1, Ch2, Ch3, Ch4
Outputs to the LED strings. The negative pins are
not identical with ground. The positive outputs are
not identical to supply power.
LED strings have to be connected between the two
pins on one channel.
4. Connecting the LEDs
The maximum number of LEDs that can be driven
by LED-Warrior04 depends on the supply voltage
and the combined forward voltage of the LEDs.
Input voltage needs to be about 2.5V higher than
the total forward voltage of the LED string for
proper operation.
Connect the LED strings between the + and -
outputs for each channel.
A LED string has to be connected to both pins
of one output!
Do not connect one end of the LED string to
supply power or ground!
Do not connect pins of two outputs together!
Do not cross connect LED strings between the
pins of different outputs!
Any configuration where one end of the LED
strings is connected to a common pin does not
work!
4.1 EMC
LED-Warrior04 has been designed to produce a
minimal level of RF emissions.
As a component LED-Warrior04 can not be EMC
approved but the EMC tests in a typical
configuration were completely unproblematic. Test
results are available on request.
The utilization of the spread spectrum PWM for
dimming does reduce RF missions generated by
LED-Warrior04.
4.2 Output ripple
Current ripple on the LED-Warrior04 outputs is in
a very high frequency range due to the fast
switching speed of the DC/DC conversion. The
actual ripple current is negligible and in most cases
complicated to measure due to its small amount
and high frequency.
