1. GENERAL DESCRIPTION
2. SAFETY CONDITIONS
PX282 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. PX282 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.
The PX282 driver is designed to control LEDs. The device has been placed inside DIN rail
housing. The built-in DMX receiver allows for activating 3 channels (R, G, B) by using directly the
DMX protocol. A wide range of supply voltage and a high level of current-carrying capacity (6A)
enable activating large quantities of LEDs.
PX282 can be controlled by the DMX signal or it can work independently.
In such operation mode, the user has access to a fully programmable scene and 18 default
sequences for which he can also change the playback speed and the smoothness of transition of
particular steps. With the use of 16-bit resolution, controlling the parameters of channels is
completely smooth. Moreover, the driver offers an effect control mode which allows for controlling
the programs that are built into the device and, at the same time, changing such parameters as
speed, brightness and fade settings using the DMX-512 signal sent from an external controller.
The driver offers a built-in control signal frequency tuning system ("flicker free" technology),
which makes it useful in applications for the television industry. As LEDs from the RGB series
often differ in parameters, problems in receiving white colour may occur (triggering 100% at all
channels). This is why the PX282 has been equipped with a very useful feature called 'white
balance.' With this feature, each set of LEDs can be adjusted so that the control of individual
colours by the module enables achieving white colour at full activation.
What is more, this feature allows for adjusting colour temperature of white output colour.
The PX282 version equipped in 6A outputs and supporting RDM protocol
has been introduced to the production starting from 14260014 serial number.
