Import 12v 80w Triac Dimmable Led Driver Waterproof — Buy in Bulk from Supplier in China

Ottima Technology Co., Ltd, based in Shenzhen, Guangdong, manufactures this 12V 80W triac dimmable LED driver under part number OTM-TD80-PHW12. The unit accepts a universal input of 100-277VAC and delivers a constant 12VDC output at up to 6.67A, with a power factor above 0.95 and full-range triac dimming from 0 to 100%. An IP67-rated enclosure makes it suitable for outdoor and wet-environment lighting installations.

The driver uses PWM output to maintain flicker-free dimming across the full range, a feature that matters for architectural and retail lighting where visual consistency is critical. Ottima states the product carries CE, RoHS, SAA, ETL, and CB certifications and backs it with a five-year warranty, though buyers should verify certificate numbers independently before relying on them for market access. The housing measures 230 × 70 × 46 mm and weighs 1.1 kg, shipping 10 units per carton.

Typical buyers include commercial lighting contractors, outdoor signage integrators, landscape lighting distributors, and OEM fixture builders who need a dimmable, weatherproof constant-voltage supply. Ottima offers custom label printing at no extra charge and can supply supporting documentation such as BOM lists, CAD drawings, and circuit diagrams on request. Confirm minimum order quantity, lead time, and whether the five-year warranty covers both the driver and the dimming electronics before finalising your purchase order.

Ottima Technology Co., Ltd operates from the Puhua Science and Technology Park in the Longhua District of Shenzhen, Guangdong, China. The company describes itself as a high-tech enterprise focused on the R&D, manufacture, and export of LED drivers, with a product range covering constant voltage, constant current, DALI, 0-10V, PWM, and five-in-one dimmable topologies. The supplier claims over 15 years of export experience in the LED driver category.

The trust tier on the marketplace is listed as harbour, and no response-rate data is currently recorded, so buyers should allow extra time for initial correspondence.

Before committing to volume, request copies of the CE, SAA, ETL, and CB certificates bearing the exact part number OTM-TD80-PHW12, and ask whether Ottima holds ISO 9001 or IATF 16949 quality management certification.
