BOD ring transformer is a major type of electronic transformer. It has been widely used in household appliances and other electronic equipment with high technical requirements. Its main purpose is as power transformer and isolation transformer. Ring transformer has a complete series abroad. It is widely used in computers, medical equipment, telecommunications, instruments, lighting, home appliance sound, electrical control, humidifier, atomizer, outdoor engineering, security monitoring equipment, etc. it has the advantages of small volume, high efficiency, low temperature rise, small magnetic leakage, easy installation and so on.

Features

1. High efficiency: high quality materials and compact structure are adopted to minimize the distance between iron core and winding, so the efficiency can reach more than 90%;

2. Small magnetic leakage: the magnetic gap of the iron core of the ring transformer is small and the winding is uniform;

3. Low noise and low heat generation: because the ring transformer is made of high-quality and low loss materials, with uniform circular section and continuous winding, the resistance loss and heat generation are very low;

4. Small overall size and light weight. The weight of ring transformer can be reduced by half compared with laminated transformer;

5. It is easy to install the ring transformer. There is only one mounting screw in the center, which is especially easy to quickly install and disassemble in electronic equipment;
