WB-MRGBW-D maximum load and best practices

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?

Yes, your calculations are correct.
48 volts and 5 amps are absolute values. At 24 volts, the maximum power (per channel) will be 120 watts.
480/14 = ~ 40
If you take 35 meters of tape and a power supply, it will work.

@SM11

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?

What is the longest run length of LED Flexible Strip Lighting? - Prism Lighting Group.

But more details are described in the manufacturer’s datasheet for each brand.
If you need to connect the LED strip longer, then it is connected with wires to the dimmer.

@SM11

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.

On the front panel of the power supply there is a “VADJ” regulator and you can compensate for the drop on the wire. ±3 volt.
But a drop of only 1-2 volts will be imperceptible even without compensation.

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

The hardware RS-485 port supports the required operating speed of 250,000
Our users are successfully using the controller to transfer using Python scripts:

Поддержка dmx512

Проект коммерческий но штучный, поэтому бюджет ограничен, если получится с поддержкой dmx купим под объект 4 контроллера. Я нашел код на python, и как понимаю порт rs485 должен поддерживать скорость 250 000 для возможности передавать DMX сигнал, что подскажите? def sendDMX(data): import serial # Make a DMX packet out of the data dmxPacket = chr(0x00) + ''.join(chr(element) for element in data) # To create sync signal (break and mark after break, in DMX-speak), # slow port down and send a …

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?

The required functionality can be described using JS scripts (wb-rules) in the controller.
