## **Current Sense Transformer** 

## **CST25-0050** 

## **Description:** 

Triad's CST25 series of current sense transformers are ideal for monitoring currents in high frequency applications such as switch-mode power supplies, LED lighting, etc. The CST25 series is offered with a built-in sense winding allowing for ease of use. These current sense transformers are fully encapsulated allowing for a high isolation of 4000 VAC between primary and secondary windings. 

## **Construction:** 

Constructed with UL rated 130°C (Class B) materials. 

## **Electrical Specifications (@25°C) @ 10kHz, 0.01V**
