2-Pin Micro Current Transformer
We can make very small size current transformer for PCB mounting, with height and width less than 20mm. The 2 pins of standard pitch make it can be easily assembled and soldered. We can also manufacture other customized PCB mount current transformers with different turns ratio and max. current. 2-Pin Micro Current Transformer Features Current transformer of compact size High […]
» Read moreRing Type Current Transformer Structure
By comparison with busbar type current transformer (CT), the structure of ring type current transformer is simple. Usually, there is a through-hole of no less than 8mm diameter, which allows the primary wire or copper busbar come through. The through-hole may be “I” type or “+” (cross) type, which can fix the busbar properly and make it’s very easy to […]

Coronavirus Impact on Current Transformer Delivery
From middle January this year, the spread of fatal coronavirus in China has attracted nearly everybody’s attention. We prolonged our holidays of Chinese New Year, postponed the reopening of our office and factory. Now, we still haven’t achieved our maximum production capacity of miniature current transformers, as some of the workers are in the condition of isolation after coming back […]

Miniature current transformers are important components for a variety of areas in the industry. Technical jargon is the keyword for ordering mini current transformers. It’s also important to be familiar with the structure of a typical product. According to the Chinese Industry Standard, many technical terms have been defined. Here we introduce some of these terms and give detail explain. Instrument […]

PCB mounting type current transformers of 4-pin or 2-pin with standard pitches can be easily installed in energy meters, test instruments and so. The most common type is one with through-hole, for which primary wire or busbar can put through. As high permeability soft magnetic cores are adopted, we can provide PCB type CT with very low phase tolerance and […]

Mini Current Transformer: Production Process
Miniature current transformers (CTs) play an important role in the electrical devices for measurement or protection, such as electricity meters, smart grid, and other electrical instruments. As a professional manufacturer with more than 15 years experience, we introduce the production process of a typical current transformer as below. Of course, different kinds of current transformer may vary a little during […]
