1 Description
The PX783 current driver has been designed for LED control.
The built-in DMX receiver allows for controlling 4 channels (e.g. R, G, B,
W) using the DMX protocol directly. The wide range of power supply voltage
(12 – 48V DC) and high current-carrying capacity (max. 700mA) enable
controlling high numbers of LEDs.
The PX783 can be controlled the DMX signal and it can work on its own.
In this case, the user has a fully programmable scene and 18 pre-programmed
sequences for which the playback speed and smoothness of step changing
can be freely set.
Driver PX783 can operate in different control modes: 2b – brightness and
one of the 256 colors define by the manufacturer, 3b – each color RGB can be
set separately, 3bd – each color RGB can be set separately and dimmer
(dimming all outputs), 4b – each color RGBW can be set separately, 4bd –
each color RGBW can be set separately and dimmer (dimming all outputs) HSL
– responsible for hue, saturation and lightness, dW – dynamic white, control
channels cold and warm white, EFF – it is available on 8 DMX channels and
control R, G, B, W, Mode, Speed, Fade and Brightness.
The driver has a built-in “ flicker free ” frequency control system, which
makes it especially suitable for use in the television industry.
The RGBW LEDs often differ quite substantially in parameters, this can
cause problems in obtaining a white color (at full power especially). Therefore
PX783 comes with a very useful function called "white balance". Thanks to it
