Description

Driver LED 3 x 700mA with built-in DMX512 signal receiver is designed to 

control LEDs. The built-in DMX receiver allows for activating 3 channels (R, G, 
B) by using directly the DMX protocol. The device has been placed 

in a 

housing adapted for mounting on a 35mm DIN rail. A wide range of supply 
voltage and a high level of current-carrying capacity enabled activating large 
quantities of LEDs.

PX781 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 can be 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 
DMX512 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 color may occur (triggering 100% at all channels). This is why 
the PX781 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 colors by the module enables achieving white color at full
