1. GENERAL DESCRIPTION
2. SAFETY CONDITIONS
PX254 LED Driver 3 x 6A OC is a device powered with safe voltage 12-24 V; however, during its
installation and use the following rules must be strictly observed:
1. The device may only be connected to 12 - 24 V DC with current-carrying capacity compatible
with technical data.
2. All the conductors should be protected against mechanical and thermal damage.
3. In the event of damaging any conductor, it should be replaced with a conductor of the same
technical data.
4. Connection of power supply can only be made with a conductor of minimum cross-section area
2
of 2,5mm and DMX signal with shielded conductor.
5. All repairs and connections of outputs or DMX signal can only be made with cut off power
supply.
6. PX254 should be strictly protected against contact with water and other liquids.
7. All sudden shocks, particularly dropping, should be avoided.
8. The device cannot be turned on in places with humidity exceeding 90%.
9. The device cannot be used in places with temperature lower than 2°C or higher than 40°C.
10. Clean with damp duster only.
PX254 driver is designed to control the LEDs. Built-in DMX receiver allows to control 3 DMX
channels (R, G, B) directly with the DMX protocol. Wide range of power supply voltage and high
current carrying capacity outputs (6A) permit a control of large quantities of LEDs. What is more
the PX254 has built-in fuses that can be replaced by the user by himself.
PX254 can be either controlled by DMX, and act independently. In this case, the user is offered a
fully programmable scene and 18 pre-programmed sequences, which can also freely change the
playback speed and fluidity changes in steps. By using 16-bit resolution control of each channel
is completely smooth. In addition, the PX254 driver gained control mode called effect mode to
control the programs built into the driver and the simultaneous change the settings of parameters
such as speed, brightness and fade using DMX-512 signal sent from the external controller.
The driver has a built-in tuning frequency signal system ("flicker free" technology), which makes it
particularly useful in applications for the television industry. The RGB LEDs often differ quite
substantially in parameters, this can cause problems in obtaining a white color (at full power
especially). Therefore PX254 comes with a very useful function called "white balance". Thanks to
it you can choose color correction for each set of LEDs controlled by the device to achieve at full
power the color white. What's more, this feature also allows you to adjust the color temperature of
white color.
The PX254 is produced in common anode version - it allows LEDs connection on common
anode.
