V-Auto -- leftover Power Supply Exchange English how-to
English leftover 1-page A4 AM.CO.ZA wiring how-to from the local cncu.co.za V-Auto-Vinyl-Cutting-Plotter product root. Authoring app Microsoft Word for Microsoft 365; created 2023-08-18. Identifies two AM PSU SKUs and the AC/DC rewire map used when exchanging a V-Smart / V-Smart+ / V-Auto power supply. Cite original source. Distinct MD5 and size from the already-copied larger V-Smart-tree export of the same title (manuals/vsmart/V-Smart-V-Smart-Plus-and-V-Auto-Power-Supply-Exchange.pdf, 303089 bytes, MD5 CABFBFE70BD65A76EFAECD1B6C0FCFE6; live V-Smart HEAD 200 303089). This V-Auto-tree copy is unused leftover English (not an FTDI twin; not a size/MD5 twin). No pricing stored.

Full English digest of the sheet (both PSUs, photos and rewire legend)
The PDF is a single A4 page with three blocks: a header row and photo for each of the two power supply units, then a short "Rewire as" legend. Re-read 2026-10-19 from the public cncu.co.za copy (230031 bytes, MD5 9B3E2C77F43FC34D715BAEEB857F24DD, same as the local mirror). There is no other text on the page.
V3-POWER.2013: 5V / 12V / 36V, V-Smart series 2013+
- Header row: small thumbnail, the SKU V3-POWER.2013, and "Power Supply Unit (5V/12V/36V) for V-Smart Series Vinyl Cutter 2013+ Model".
- Photo: an enclosed metal-cage (perforated cover) switching power supply seen from the terminal side.
- One 7-way screw terminal strip. Printed labels from left to right: L, N, E, 12V, 36V, GND, 5V.
- So this older unit has three AC terminals (L, N, E) and four DC terminals, with a single GND screw shared by all DC rails.
V3-POWER.2018: 5V / 13V / 36V, V-Smart, V-Smart+ and V-Auto 2018+
- Header row: small thumbnail, the SKU V3-POWER.2018, and "Power Supply Unit (5V/13V/36V) for V-Smart, V-Smart+, V-Auto Vinyl Cutter 2018+ Model".
- This is an open-frame green PCB unit with plug-in headers instead of screw terminals.
- Left photo (AC input corner): a 3-pin white header with silkscreen N, L, FG beside the pins, next to a small board-mounted fuse and the input filter parts.
- Right photo (DC output edge, AM.CO.ZA watermarked): a 6-pin white header marked CN2 with silkscreen, left to right, 5V, GND, GND, GND, 13V, 35V. Large 1000 uF 35 V filter capacitors sit behind it and LED1 is the power indicator.
- A separate small 2-pin header to the right of CN2 is marked - +. The sheet's legend does not mention it, so it is not part of the rewire.
Rewire as (the sheet's legend, in full)
- AC: L = Live (220V+), N = Neutral (220V-).
- AC: E = Earth = PE = Protective Earth = FG = Frame Ground (the 2013 unit says E, the 2018 board says FG; they are the same earth connection).
- DC: 5V = 5V, 13V = 13V, 35V = 36V, GND = GND (the 2018 board prints 35V on the pin that carries the 36V rail).
Terminal map when fitting a V3-POWER.2018 in place of a V3-POWER.2013
The sheet lists only the name equivalences above. Laid side by side, the two terminal sets line up like this (the 12V-to-13V line is read from the two labels, not printed as a separate instruction):
| Old V3-POWER.2013 screw terminal | New V3-POWER.2018 pin | Notes |
|---|---|---|
| L | AC header L | Live (220V+) |
| N | AC header N | Neutral (220V-) |
| E | AC header FG | Earth / Protective Earth / Frame Ground |
| 12V | CN2 13V | The 2018 unit supplies 13V on this rail |
| 36V | CN2 35V | Labelled 35V on the board, same 36V rail per the legend |
| GND | CN2 GND (any of the three) | One GND screw on the old unit, three GND pins on the new header |
| 5V | CN2 5V | 5V logic rail |
Practical notes
- Unplug the cutter from the wall before opening it; the AC side runs at mains voltage.
- Mark or photograph each wire on the old terminal strip before removing it, then move them one at a time to the matching pin in the table.
- Earth (E / PE / FG) must stay connected to the frame; never leave it off.
- Leave the extra 2-pin "- +" header alone unless the machine already uses it; the sheet does not route anything to it.
- The matching AM.CO.ZA PSU and cable listings are V3-POWER https://buythis.co.za/v3-power#ai, V3-POWER/CABLE https://buythis.co.za/v3-power-cable#ai and V3-POWER/CABLE/S https://buythis.co.za/v3-power-cable-s#ai.

Software / drivers
No PC installer for this hardware PSU how-to. FlexiSTARTER / VinylCut / SignMaster / FTDI / firmware-upgrade EXEs remain URL-only prior. No new V-Auto controller firmware this pass (quiet; still 2 packages; prefer 004.33F; binaries URL-only; Firmware//Firmwares/ 404 -- use V-Auto Firmware Upgrade Software). See drivers/vauto-software-notes.md and drivers/vauto-firmware-index.md.
