1. GENERAL DESCRIPTION
2. SAFETY CONDITIONS
Px307 LED Driver 3 x 700 mA is a device powered with safe voltage 12-24V; however, you should
at all times obey the rules set forth below:
1. The device may be connected to 12 - 24V DC (stabilized voltage) with current-carrying
capacity compatible with technical data only.
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 parameters.
4. Connection of DMX signal can be made with shielded conductor only.
5. All repairs and connections of outputs or DMX signal can only be made with cut off power
supply.
6. PX307 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 PX307 driver is designed to control LEDs. The device has been placed inside metal
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 enable
activating large quantities of LEDs.
PX307 can be controlled by the DMX signal or it can work independently.
In this operation mode, the user has access to a fully programmable stage and 18 default
sequences for which he can also change the reproduction 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 PX307 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.
PX307 has also been equipped with a function of temperature power output limit and
connectors for connecting a temperature sensor.
