About CHUGAO
Zhongshan Chugao Electronic Technology Co., Ltd. makes LED switching power supplies in a 6,000 m² factory in Guzhen, Zhongshan — the lighting manufacturing hub of China. We run 38 people on the floor and 8 in sales, shipping to 42 countries across Europe, North America, the Middle East, and Southeast Asia.
m² Factory
Guzhen, Zhongshan — China's lighting capital, with the full supply chain next door.
Floor staff
Skilled SMT, wave-soldering, potting and QC operators on four dedicated lines.
Countries
Distributors, brands and contractors across Europe, North America, the Middle East and SE Asia.
Trading since
Over 15 years building LED drivers and AC/DC adapters for global buyers.
Product lines
Adapters, indoor drivers, IP67 and IP65 — one stop for low-voltage LED power.
Burn-in
Every unit runs a 48-hour full-load burn-in before it is packed and shipped.
What we make
Four product lines cover most low-voltage LED jobs: AC/DC adapters (5-200W), indoor LED drivers (50-400W), IP67 waterproof drivers (10-400W), and IP65 rainproof drivers (100-600W). Together they run everything from a short strip behind a shelf to a weatherproof sign outside a shop.
Every unit passes 48 hours of burn-in before it ships, and carries CE and RoHS as standard. UL and BIS are available per model for the North American and Indian markets.
Product lines at a glance
Four lines, one factory. Each runs on the same SMT and potting lines and is tested to the same 48-hour full-load burn-in before it ships. Open a line for full specs, popular models, and the certificate options for your market.
Adapters · 5-200W
AC/DC adapters for LED strips and modules. Wall-mount and desktop. DC 12/24/36/48V. CE, UL on request.
Specs →Indoor drivers · 50-400W
Fan-less indoor LED drivers with built-in PFC. For ceiling and panel lights. Triac / 0-10V dimming on selected models.
Specs →IP67 waterproof · 10-400W
Sealed drivers for wet and outdoor use. -30 to +60°C. Signs, facades, fountains.
Specs →IP65 rainproof · 100-600W
Rainproof drivers for semi-outdoor signage cabinets. Higher wattage, airflow cooling.
Specs →Manufacturing & quality control
Production runs on four dedicated lines fed by SMT assembly and wave soldering, then finished on in-house potting and enclosure lines. Each driver moves through incoming component inspection and automated ICT, then a 48-hour full-load burn-in at elevated temperature before it is packed. On the line we check output voltage, ripple, efficiency, and the four protective functions — over-voltage, over-current, over-temperature, and short-circuit — so a weak unit is caught before it reaches you.
Automated assembly
Surface-mount and wave soldering with automated optical and in-circuit inspection.
In-circuit test
Every board is tested for shorts, opens and component values before potting.
Full-load burn-in
Units run at full load in a hot chamber so early failures show up before shipping.
Four protections
Over-voltage, over-current, over-temperature and short-circuit protection on every model.
Engineering & customization
Our engineering team supports OEM and ODM changes to output voltage, enclosure size, connector type, and cable length. Where a project calls for it, we can add dimming control (0-10V or PWM) or adjust the input range. Custom samples are built from your spec sheet and verified against the same test routine used in mass production, so what you approve is what ships.
Global markets & support
We supply distributors, lighting brands, and project contractors in 42 countries, with the strongest presence in Europe, North America, the Middle East, and Southeast Asia. Sales and engineering reply in English, Spanish, French, Russian, Arabic, and Chinese, and aim to respond within 1 hour during China business hours (GMT+8).
Certificates follow the destination market: CE and RoHS for Europe, UL for North America, BIS for India, and CB / ENEC where required. Every shipment leaves with a commercial invoice, packing list, certificate of origin, and the model-specific test reports, with original documents sent together with the goods.
OEM and ODM
We build custom drivers for clients in Germany, Brazil, and Saudi Arabia. The minimum is 500 pcs for custom tooling, and tooling is free on repeat orders over 2,000 pcs. Send us your spec sheet and we return a quote, a sample lead time, and the certification plan for your target market.
Why buy factory direct
Buying from the manufacturer removes the trader margin and shortens the path from a design change to shipment. You can also request the exact certificate package your market needs instead of a generic one. Every shipment includes a commercial invoice, packing list, certificate of origin, and CE/RoHS reports, with original documents shipped with the goods.
Exhibitions & trade shows
We exhibit at major LED and lighting trade shows every year, meeting distributors and brand owners face to face. The photos below are from our booth appearances at the Zhongshan Guzhen, Guangzhou, Canton Fair, and Shanghai lighting exhibitions between 2018 and 2024 — the team on the floor, the products on display, and the conversations that turn into long-term supply partnerships.
