Import 30w Junction Box Triac Dimmable Led Driver — Buy in Bulk from Supplier in China

The OTM-TDJ30 series from Ottima Technology Co., Ltd is a 30W junction box triac dimmable LED driver available in 12Vdc and 24Vdc constant voltage outputs, housed in a metal junction box enclosure rated to IP54. Input voltage accepts either 100-277Vac or 180-240Vac depending on regional configuration, with a power factor greater than 0.95 and triac dimming compatibility across 0-100% range. The unit delivers 2.5A at 12V or 1.25A at 24V, utilising PWM output to preserve colour rendering index stability throughout the dimming curve.

The driver employs free air convection cooling and carries full protection against short circuit, overloading and over temperature conditions. The metal junction box construction suits dry and damp locations, with SELV classification and flicker-free operation. Ottima offers logo printing on the driver label at no additional cost. The 7-year warranty period exceeds typical industry coverage for consumer-grade LED drivers, reflecting confidence in thermal management and component selection.

Applications span residential retrofit, hospitality lighting, retail display and architectural fixtures where triac dimming infrastructure already exists. The forward and reverse phase compatibility (leading and trailing edge) allows integration with existing MLV, ELV and conventional triac dimmer inventories. Buyers should confirm whether their target market requires the 100-277Vac or 180-240Vac input variant, and verify local dimmer compatibility through sample testing before committing to bulk orders.

Ottima Technology Co., Ltd operates from Floor 4, Building 1, Puhua Science and Technology Park in Shenzhen's Longhua District, Guangdong Province, placing it within China's densest LED driver manufacturing corridor. The company positions itself as a high-tech enterprise focused on R&D, manufacture and export of DALI LED drivers, multi-protocol dimmable drivers and junction box LED drivers. Its product range concentrates on power electronics for solid-state lighting rather than broad diversification into fixtures or controls.

The listing carries Harbor trust tier status, though both response rate and average response hours register at zero, suggesting limited engagement data on this channel. Buyers should treat direct communication as essential to confirm production schedules, sample availability and current certificate validity. The supplier maintains an independent web presence at ottima-power.com, which may offer additional technical documentation beyond what appears in this listing. No information is provided about factory size, annual output, key accounts or years in operation, so due diligence on manufacturing capability remains the buyer's responsibility.
