ROE Visual DM3.9: 3.91 mm pitch, 500 by 500 mm cabinet.
Cabinet geometry, weight, and power for the ROE Visual DM3.9, plus a calculator that turns a target wall size into cabinet counts, resolution, weight, and circuit loading.
Estimated specs. Lightweight indoor ROE preset. Verify exact DM3.9 cut sheet. Verify against the manufacturer cut sheet before ordering.
Pixel pitch 3.91 mm, 16,384 pixels per cabinet at 128 by 128
Cabinet 500 by 500 mm (1.64 by 1.64 ft), 80 mm deep
7.5 kg (16.5 lb) per cabinet, about 30 kg per square metre
140 W peak per cabinet, 70 W average, about 560 W per square metre at peak
13 cabinets per 20A 120V circuit, 21 per 16A 230V circuit, at peak draw
The ROE Visual DM3.9 is indoor 3.91 mm pitch LED with a 500 by 500 mm cabinet carrying 128 by 128 pixels. Each cabinet weighs 7.5 kg (16.5 lb) and draws up to 140 W.
Those four numbers drive everything else on a build: how many cabinets reach your target size, what the wall weighs on the rigging, how many circuits the distro needs, and what resolution the processor has to feed.
Pixel pitch: 3.91 mm
Cabinet resolution: 128 by 128 (16,384 pixels)
Cabinet size: 500 by 500 mm
Brightness: 1500 nits
Refresh rate: 3840 Hz
Typical processor platform: Brompton
Power and circuits for the DM3.9
At the 140 W peak figure, one 20A 120V circuit carries 13 cabinets and one 16A 230V circuit carries 21. Both numbers apply the 80 percent continuous load derate (NEC 210.20, IEC 60364), which is the same maths WireFlow uses when it sizes a real wall.
Size the distro on peak, not average. Average draw of 70 W tells you what the wall costs to run over a show; peak is what trips a breaker during a white flash.
Peak per cabinet: 140 W
Average per cabinet: 70 W
Cabinets per 20A 120V circuit: 13
Cabinets per 16A 230V circuit: 21
Input voltage: 100 to 240 V at 50/60 Hz
Worked example: a 4 by 3 wall
12 ROE Visual DM3.9 cabinets in a 4 wide by 3 high grid make a wall 2 by 1.5 m (6.56 by 4.92 ft) at 512 by 384 pixels.
That wall weighs about 90 kg before rigging hardware and draws up to 1,680 W, which needs 1 circuit at 20A 120V or 1 at 16A 230V.
Wall size: 2 by 1.5 m
Resolution: 512 by 384 pixels
Weight: about 90 kg
Peak draw: 1,680 W
Circuits: 1 at 20A 120V, 1 at 16A 230V
Build this wall in WireFlow
The calculator above sizes a wall to your target dimensions with this panel's real cabinet geometry, then reports cabinet count, resolution, weight, and circuits. From there WireFlow can drop the finished wall straight into a diagram, already wired to its processors, and the cable schedule and power report update with it.

Frequently asked questions
What is the pixel pitch of the ROE Visual DM3.9?
3.91 mm. Each 500 by 500 mm cabinet carries 128 by 128 pixels, or 16,384 in total.
How much power does the ROE Visual DM3.9 draw?
Up to 140 W per cabinet at peak, averaging around 70 W in normal content. That works out to roughly 560 W per square metre at peak. Size distro on the peak figure.
How many DM3.9 cabinets fit on one circuit?
13 on a 20A 120V circuit and 21 on a 16A 230V circuit, both at peak draw with the standard 80 percent continuous load derate applied.
How much does the ROE Visual DM3.9 weigh?
7.5 kg (16.5 lb) per cabinet, which is about 30 kg per square metre of wall. A 4 by 3 wall of them comes to roughly 90 kg before rigging hardware.
Are these ROE Visual specs exact?
Estimated specs. Lightweight indoor ROE preset. Verify exact DM3.9 cut sheet. Verify against the manufacturer cut sheet before ordering.
Can I design a wall with this panel in WireFlow?
Yes. Pick this panel, give it a target size, and WireFlow works out the cabinet grid, pixel map, weight, and power per circuit, then places the wall into your diagram already wired to its processors. Free to start with three diagrams and no card.
