High Sensitivity Current Toroidal Transformer for Small Current Precision Measurement Instruments

Yes, we support mass production of toroidal transformers with insulation grades of Class A, Class B, Class F and Class H. Different insulation grades can adapt to different working ambient temperatures, and we can recommend the most suitable configuration according to your specific usage scenario.

We partner with over 100 global authorized third-party certification agencies, to handle compliance testing, certificate of origin and FTA tariff reduction documents, helping customers save up to 30% import tariff in destination countries.

Yes, all our products are equipped with built-in overvoltage, overcurrent, overheating and short-circuit protection modules. It will automatically cut off output when abnormal working conditions occur, effectively protecting connected devices from damage.

Our toroidal transformers are widely used in high-fidelity audio equipment, medical testing instruments, new energy solar inverters, industrial automation control equipment, LED stage lighting and household voltage conversion scenarios, and can match the demand of different power levels from 10W to 10KW.

Compared with traditional EI transformers, toroidal transformers have 30% lower magnetic leakage and noise, higher conversion efficiency (up to 95% or more), and 30-40% smaller volume and weight under the same power rating. They also have lower temperature rise during long-time operation, which is more suitable for high-precision devices.
