Description

The PX789 driver is designed to control LEDs. It can be powered with 24 – 60V DC with a maximum current carrying capacity of 2.3A. It is possible to set the current (600 – 2300mA) of the output driver in accordance with the parameters of the LED receivers. In addition, an option has been implemented in the driver to accurately calibrate the output current. It should be remembered that the driver supply voltage must be at least 3V higher than the voltage of LED receivers.
PX789 can be controlled by DMX signal (the device has a built-in DMX512 signal receiver) as well as operate independently. The DMX address and other device settings are configured using PX277 (PxArt+ Settings Controller)or via RDM protocol. The user has the option of configuring the behavior of the device in the event of loss of the DMX control signal. The driver works in full analog range, despite the fact that interpolated resolution of the output control is 16 bit.
The driver also has the Offset parameter implemented, which allows to eliminate or reduce the threshold of switching on the lamp. The device supports the RDM protocol.
