CST25-1000

Current Sense Transformer CST25-1000 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. There are five different popular turn ratios available to choose from. Construction: Constructed with UL rated 130°C (Class B) materials. Electrical Specifications (@25°C) @ 10kHz, 0.01V Min. Sec.
