General description
The PIXEL DMX LED driver is a 48-channel device to control RGB LEDs (LED strips,
single diodes, modules etc.). The current loadability of every input is 500mA. Supply from
a safe source 12VDC. Ideally suited for assembly of multi-channel matrices of LED pixel -
RGB, controlled by the DMX 512 protocol. Drivers polarization enables the connection of
LEDs in a common plus system (common anode). Due to a metal housing we can install a
controller at places hard to reach. A system of separable screw joints we use facilitates
disassembly. Every LED controlled output is secured against an overload. These
protections protect not only a controller but as well a LED installation against a damage.
In case of overload only this channel is turned off where a defect occurred. With such a
defect remedied the driver is back to normal operation. Our device is also provided with
an anti-short circuit and surge protection of the DMX512 signal line. The driver is
provided with integral testing programs for a quick localization of possible assembly
mistakes. A large 9-bit control definition and dimming characteristics adapted to the
human eye sensitivity causes the lighting intensity to change in a linear and infinitely
variable way. The driver refreshing frequency PWM (Pulse Width Modulation) is 500 Hz.

Basic safety conditions
The PIXEL DMX LED driver 48 x 500 mA is a device supplied with the 12 VDC safe
voltage from a dedicated power supply, however, during its installation and use the
following rules must be absolutely observed.
The module must be made by an authorized person and according to its instruction.
The device can be connected only to a regulated voltage of a loadability according to
technical data.
The module is designed for internal use. In case it is used outside it must be protected
against atmospheric impact.
Protect all wires from mechanical and thermal damage.
Carry out all repairs with the supply switched off.
Do not connect a device to a supply source when its damages are visible.
Absolutely protect the PLD 48 against contact with water and other fluids.
Avoid sudden shocks especially against a fall.
Do not switch the device in spaces of the relative humidity above 90%.
Do not use the device in spaces, where the temperature is lower than +20
0
C or above
+40
0
C.
