Import Dimmable Electronic Transformer — Buy in Bulk from Supplier in China

These dimmable electronic transformers are designed for low-voltage halogen lamps, converting 220-240V AC input to 12V AC output with a dimming function that enables smooth light level adjustment. They operate without flicker during start-up and dimming, ensuring visual comfort in environments where lighting ambiance is critical. The unit is optimized for residential and light commercial use, with a compact form factor suitable for concealed installations.

The transformer uses a toroidal core and high-frequency switching circuitry to achieve high efficiency, typically above 85%, reducing heat generation compared to magnetic transformers. While the supplier does not specify the exact core material or switching frequency, the design follows typical industry practices for electronic transformers used with halogen lamps, including overcurrent and short-circuit protection. Output voltage stability is maintained within ±5% under varying load conditions.

These transformers are commonly sourced by lighting designers, hotel contractors, and retail fit-out firms for accent lighting, display cases, and under-cabinet applications. Orders are typically placed in batches of 100 to 1,000 units. Packaging is in blister packs or bulk cartons with individual labeling. Trade terms such as FOB Xiamen or CIF are available, but minimum order quantity and lead time must be confirmed directly with the supplier as they are not disclosed.

Mainhouse (Xiamen) Electronics Co., Ltd. is registered in Xiamen, Fujian, with a physical address at No.1219, Nanhai San Rd, Haicang. The supplier is classified as imported with a harbor trust tier, indicating basic platform verification. No website, certifications, or manufacturing details are disclosed. The company appears to act as a trading entity, sourcing and exporting electronic transformers without claiming in-house production capability.
