| All-parallel · Dot-controlled | RGB × 3 / RGBW × 4 | 9874A · 9873A | |
Key parameters
| Parameter | Options |
|---|---|
| Detective voltage | 3 V (DC < 36 V) · 3.4 V (AC 110/220 to DC) · 2.5 V (battery 4.5–6 V) |
| Voltage regulator | Full range set at 6 V |
| Signal speed | LV DC: T0L = 3 µs, T1L = 6 µs · HV: T0L = 5/10/20 µs (optional), T1L = 10/20/40 µs |
| LED driver output | Indoor: 3.5 / 4.7 / 7 mA per channel · Outdoor: 7 / 10 / 12 / 20 mA per channel |
| Connection topology | All-parallel (simple process, PWM-adjustable total power) · Serial-parallel (more lamps per supply, longer signal reach) |

Our commitment
Every PowerMOS customer is protected by this patent network. For original patent documents, write to cj@powermos.com — we are glad to have counsel address any concern raised in the market.
03 · Production
Your existing lines already qualify
- String lights — add an address writer to your existing wire-bonding automatic machine and you are producing dot-controlled products.
- Copper-wire lights — existing SMD equipment needs no change; addressing is completed with a dedicated fixture during inspection.
- PVC string lights — produced with in-line address burning, fully automated.
04 · Quality & Reliability
Numbers a sourcing manager can verify
8"Mature 8-inch process line, Taiwan IC fab
100M+Chips shipped, 3 years of market testing
6kVESD human-body-model rating
±200mALatch-up immunity at 8.25 V
Complete quality control runs on our self-owned wafer probe testing facility, and every chip carries built-in over-voltage protection with strong anti-interference capability for AC 110/220V applications.
05 · Controllers & App
A complete control ecosystem, not just a chip
Single & multi-channel
5V parallel, 12V lamp-replaceable with WiFi, 24V serial-parallel with WiFi, and 110/220V serial-parallel — for string, net and curtain lights, with MCU effect programming.
DMX512 → PLC · SPI → PLC
Keep your existing workflow: edit in LEDBuild (select APA104 and the converter translates automatically) or drive strings from any standard DMX512 controller. Variants from single-port 110/220V to a bulb-replaceable 4-port version.
Up to 96 ports · 5,760 lamps
SD-card and SPI-flash master/slave systems: 24V or 110/220V 24-port boards driving 2,400 lamps, and a 5V 96-port curtain-light controller driving 5,760 lamps over Ethernet cabling.
Design freedom
Graphics can be authored in the tools your team already uses — Photoshop, Illustrator, Premiere, After Effects, Cinema 4D, Maya, Unity, 3ds Max — then converted for playback. Mobile apps cover string, curtain and net lights, with WiFi, Bluetooth and Alexa compatibility.
