Import 220v 24v Toroidal Power Transformer — Buy in wholesale FOB from Supplier in China

Tianjin Grewin Technology Co., Ltd. offers a 220V 24V toroidal power transformer range with model codes running from GWB25VA up to GWB500VA. The source data gives detailed technical parameters for this series, including a 135 degrees C thermal fuse, current fuse ratings of 250V T 2A, 5A or 10A depending on model, and dimensions from 80 x 35 mm for GWB25VA to 155 x 62 mm for GWB500VA. Approval marks listed in the source are CE, UL, TUV and CQC across the range. This is a more specification-led listing than a generic transformer page, which helps buyers match power level, protection arrangement and physical size to equipment design.

The listing also states 100% copper core and mentions customised audio toroidal transformers and solar energy transformers. Typical toroidal transformer buying criteria in this category include VA rating, secondary voltage tolerance, regulation under load, no-load current, no-load loss, dielectric strength and temperature rise, and the source confirms several of these are tested. The named test process includes no-load voltage, no-load current, no-load loss, inductive voltage test, load test, temperature rise test, insulated resistance, hi-pot test, leakage inductance test, DC resistance test and surface inspection. That level of test disclosure is useful for OEM and control equipment buyers who need routine electrical verification rather than a simple voltage label.

Applications listed for this 220V 24V toroidal transformer include audio equipment, electric control, computers, solar devices, telecommunications and video equipment. Buyers can source this range by selecting the power class first, since the physical diameter and height increase across the GWB series and the fuse rating changes from 2A to 5A and then 10A. The listing does not show MOQ, lead time, packing details or current Incoterms, so those trade terms need to be confirmed directly with Tianjin Grewin Technology Co., Ltd. before sampling or bulk purchase.

Tianjin Grewin Technology Co., Ltd. is the supplier named on this transformer listing, with an address shown as 2# Meinian Plaza, No.16 Dongting Road, Tianjin 300222, China. The available profile data shows a trust tier of harbor. No supplier tier, factory size, employee count or export volume is stated in the provided data. The listing itself is notable for including a large technical table rather than only promotional language.

The response indicators shown here are limited, with response rate recorded as 0.00 and average response hours recorded as 0. Buyers should therefore verify communication turnaround, drawing support and after-sales technical contact before committing to a project schedule. The source description mentions approvals and a test process, but the profile data does not independently show document numbers or model-by-model certificate scope, so those should be requested directly from Tianjin Grewin Technology Co., Ltd. during technical review.
