Conference table power is where furniture makers and AV integrators most often guess instead of calculate. Too few modules and the table fails users; too many and you burn budget and cable space. Here is the four-decision framework we use with OEM customers — follow it and the math takes care of itself.
Decision 1: How many modules per seat?
Rule of thumb: one module per two seats. A 10-seat conference table needs 5 power modules; boardroom and executive tables should go one-per-seat. The carrier depends on budget — motorized pop-up (ZSE) for premium lines, pneumatic (ZST) for volume projects, flip-up (ZSP) when multimedia density is high.
Decision 2: Which charging interfaces?
| Interface | Reference spec | Best for |
|---|---|---|
| AC outlets | 110-250V, switchable US/UK/EU/SA/IN/IL standards | Every project — mandatory |
| USB-A | 5V/2.4A standard; 20W A+C combos typical | Rooms with many legacy devices |
| USB-C PD | 20W baseline; 65W charges laptops | Any room built after 2020 — first choice |
| Qi wireless | 15W Qi protocol | Premium boardrooms, hotel front desks |
Recommended baseline: each module = 2 AC + 20W USB-A+C. Add one "hero module" per table with 65W PD or 15W Qi wireless (ZSO wireless charging series) for laptops and flagship phones.
Decision 3: Do you need HDMI / RJ45?
Only when the table is hardwired to a projector, display or intranet — training rooms and command centers, mostly. The ZSP flip-up and ZS06 series both accept HDMI + RJ45 modules. If the room uses wireless screen sharing, skip them and reallocate the budget to higher-wattage USB-C.
Decision 4: What installation numbers must you verify?
- Cutout size: ZSE round D=100mm; ZST round D=100–113mm; ZSP rectangular 242–427×104×103mm. Always request the CAD cutout drawing for your exact model before production.
- Under-desk clearance: pop-up bodies are 100–150mm deep — keep 150mm+ free space plus cable bend radius. Desks with stretchers should use sliding or clamp-mount (TB series, no cutout).
- Cable routing: run all module tails through under-desk metal trays; separate power and signal trays so HDMI stays noise-free.
Sample BOM: 10-seat conference table
- 5 × ZST pneumatic pop-up modules (2 AC + 20W A+C), plug standard per destination market
- 1 × ZSO wireless charging module (15W Qi + USB-C PD) at the head seat
- 2 × ZSG brush cable cubbies for permanently routed AV and phone lines
- All 110-250V full voltage, CE/UKCA certified, OEM branding available
