I’m planning to use WB-MRGBW-D to control a 24V RGBW LED strip and would like to ask a few questions regarding itself as well as RGBW led dimming using the Wiren Board controller in general, please.
I see that the driver is good for 5A at 48V per channel, which means the maximum power should be 240W per channel. What is the maximum LED strip length at 24V when the power consumption is 14W/m?
Am I correct in thinking that the maximum power at 24V would be 120W per channel and thus this would be 4ch x 120W = 480W / 14W/m = 34.29m minus let’s say 15% for safety and efficiency? If yes, I should be good with a 480W power supply such as MW SDR-480-24 and 30 metres of the LED strip, correct?
What is the maximum LED strip length you would recommend to power from one point in order to keep the voltage drop across the strip below let’s say 1V?
Could you please advise what’s the greatest length of cable from the driver to the LED strip you would recommend under these conditions?
I want to install the strip metres away from the distribution board and since sections of the strip will presumably have to be connected in parallel, I expect the length of the cable to reach about 5 – 20 metres which should result in a voltage drop across a 2.5mm2 (AWG 14) wire at 24V and 5A of about 0.4 – 1.6V, which is a lot, if my calculation is correct.
For the reason above, I’ve been wondering whether it wouldn’t be better to bring 230V AC power all the way to the strip and then use a DMX512 driver. Do you have software support for DMX512? I found it mentioned in the documentation but apparently only in early revisions of the controller. I’m asking for DMX512 because I plan to use it for a light which already has a DMX512 interface and thus it would make things easier.
Do you have software support for LED strips which allow you to control the colour temperature of white light using cold and warm LEDs? I believe these require two channels plus power, so essentially if I connected two such strips to the WB-MRGBW-D (one to RG and power, the other two BW and power), would it be difficult to control the colour temperature of each individually using a slider, for example?
