NODE Power 8

Power Injection & Distribution · 8 Fused Outputs

Put the volts back where the long run ate them.

At a Glance

• 8 fused injection outputsV+ / GND per port, individual blade fuse on each
• 5–48 VDC input, no jumpers5 / 12 / 24 / 36 / 48 V systems, nothing to set wrong
• 30 A through the board at standard coppernot a paid upgrade
• The same protected front end as every NODEtransient clamp, active reverse-polarity block, main fuse
• A fuse and a status LED on every outputthe dead tap shows itself
• Non-destructive reverse-polarity protectionnothing is consumed when someone wires it backwards
• Pure power — no data, no firmwareyour pixel data runs through the strip; this just feeds it
• Smaller than the controllersrides in the enclosure, or lives out at the injection point

Fuses — up to 30 A max input · 7.5 A blade fitted, 10 A max per output — Keystone 3568, user-replaceable

Why This Exists

Copper drops volts. Long runs go dim.

At 12 V, a long pixel run browns out before it ends. The first pixels are full white; by the far end they sag dim and off-colour, because the thin copper inside the strip dropped the voltage on the way down. Past roughly sixteen feet you cannot win it from one end no matter how fat the feed — the strip itself is the resistor.

NODE Power feeds fresh, fused power into the middle or the far end of the run, so the last pixel sees the same voltage as the first. Eight ports means eight injection points from one board — each one fused on its own, so a shorted run out at the eaves opens one fuse and the other seven never flicker.

Where It Goes

One rule either way: keep the injection board on the same supply and ground as the controller driving those pixels. One PSU per box means injected power shares a ground reference with the data — no ground loops, no back-feeding, no diode-OR games. It just works.

The Architecture · Three Power Domains

Same protection as the controllers. Just power.

An injection board sees exactly the abuse a controller does — the same reversed supplies, the same transients, the same shorted runs out in the weather. So it gets the same front end. Whatever arrives at the terminal is split into three domains on their own copper planes:

Voltage Headroom

Rated 5–48 V. The whole range is yours.

There is no buck regulator on this board to cap the input, so it runs the full range the controllers can't — right up to 48 V. At 12 to 36 V the entire power path sits with wide margin. At the full 48 V the semiconductors still run comfortably — pass MOSFET at 80%, ideal-diode controller at 60% of rating — and the 50 V bulk reservoir is sized for the job rather than for a spec-sheet trophy.
