Import Electronic Transfrmer — Buy in Bulk from Supplier in China

Sichuan Chongzhou Hengda Electronic Factory produces toroidal electronic transformers designed for efficiency and compact integration in industrial and telecommunications equipment. The products are specified for power ratings from 5VA to 20KVA, with core construction using cold-rolled grain-oriented silicon steel. These transformers are engineered to minimize electromagnetic interference and maintain stable output under fluctuating loads, making them suitable for precision control systems.

Typical core shapes are toroidal, with winding density optimized for low no-load losses. Standard insulation systems use Class B or Class F materials, with impregnated varnish for moisture resistance. Copper windings are standard, with no mention of aluminum alternatives. The supplier does not specify tolerances for voltage regulation or temperature rise, but industry-standard values for toroidal units apply: ±3% voltage regulation under full load and 60K temperature rise for Class B.

These transformers are used in automation controllers, LED lighting drivers, and renewable energy inverters. Buyers in industrial sectors require consistent performance under continuous duty cycles. Packaging is in corrugated boxes with internal padding. Lead time and MOQ are not stated in the source. Trade terms like FOB or CIF are mentioned generically but not confirmed for this supplier. Buyers must request specific Incoterms and payment terms directly.
