4 Channels DMX LED Dimmer ,

 

Introduction:
      

YM-HD4P is a Constant current DMX512 Decoder and driver for RGBW high power led lights. By advantage of advanced coding technology, the unit is compatible with international DMX512/1990 standards, which decodes the international popular digital control signals into a PWM signal to drive RGBW LED lights. Each channel can be controlled with 256 level gray-scales.

 

Specification and Parameter:

Grey Scale: 256 levels

Input voltage: DC9V-36V

Output Current : 350 mA /Channel*4(all positive)

Output Power:  28W max

Signal input :  DMX512/1990

Signal Output : constant current PWM*4Channels

Driving LED number: 5-7pcs /channel, (1Watt high power led lamp)

Consumption: <1W

PCB Size: 53*30mm

Features:

 

1. Perfectly compatible with international DMX512/1990 standards.

 

2. Differential signal transmission, support 3 mode of data transmission:

 

 

3. Display effects:

If connected to DMX512 led controller or DMX512 console, the effects will follow the DMX512 led controller or DMX512 console, and change color per their commands.

If not connected to DMX512 led  controller or DMX512 console, the effects will for pre-load program in side of the decoder.

4. Connection in Parallel
Each decoder is connected on DMX512 signal bus in parallel. It is recommended that signal amplifiers should be used for every 32 pcs of decoders in case of signal drop(Attenuation).

5.Strong anti-interference ability, anti-static and prevent lightening design.
 

Application:

 LED project light, LED Wall washer, LED ground light, LED Ceiling light, Channel light, LED Guardrail tube, full color RGB lights and LED point source lights.

 

Input & Output:

 

 

POUT PIN: PIN is program input, POUT is program output.
 D+, D-, GND:  input signal of DMX512,
 Power+ and Power-:  Power supply, Power+ is positive and Power-(GND) is ground( negative).
 V+, R, G, B,W:  RGBW Output, V+ is common anode of output.
