DDS874 300W RGBW Constant Voltage PWM

DDS874 is a DMX / RDM OneWire controller with two outputs, and a PWM 4 output in constant Voltage. This driver deliver up to a maximum total of 300W, so it is able to supply two flexible strip FLEX737, or 4 PWM constant voltage output at  maximum  300 W in total at 24Vdc, with  positive common.The 4 PWM output power supply constant voltage and OneWire, are electronically protected, in case of short circuit the FAILURE Led lights up and turns off the output with short-circuit, is solved as soon as the short circuit or the exceeding of the maximum current, the power is restored automatically.The One Wire allows control of flex reel DDS737 5 meters in single meter with DMX address, getting 15 DMX channels each reel. This module is designed to be powered by both AC and DC, and control emergency mode via special input, which activates all the 4 channels at 100%, for use of DMX / RDM as emergency light.The DMX / RDM is optically insulated from the power supply, and buffered, in the event of failure of the DDS874 module, a relay closes a contact between input is output, this  by-pass of the DMX that comes out directly on the connector the DMX/RDM, in case the module is able to work correctly, this by-pass is opened and all works normally.
This device replace DDS757 with double power.
