DDS674 4 channel costant current can supply up to 14 led in series @48vdc 600mA.
This module can work in several mode DMX/RDM and stand alone.
The DMX/RDM polarity is self corrected by the board also if wrong connection.
The current output can be programmed by RDM from 200mA up to 600mA and it is also possible monitoring led connection or led malfunction thru RDM.
The current mode is hysteretic to guarantee the best light dimmering perfomance also at 16Bit control.
Control Frequency PWM can be varied from default 240Hz up to 1,2Khz. this is for flikker free feature.
All output are positive common.
The power supply is applied to connectors a fuse is provided for overvoltage protection.
Voltage dropout is 3v, the maximum voltage regulation is Vsupply - 3V, this must be considered for maximum led per channel calculation.
A thermal protection on board is provided, in case of temperature rising at 80 degree ambient start to decrease current to LED.The max temperature peak is recorded and can be read by RDM, same for number of worked hour of the product.
