TRIAD MAGNETICS CST3063A Current Sense Transformer

The Triad Magnetics CST306-3A current sense transformer is a robust solution for monitoring current in switching power supply systems. Designed for reliable performance, it operates effectively within a frequency range of 20 kHz to 200 kHz. Constructed with UL-rated 130°C materials, this transformer ensures safety and durability in demanding industrial environments. Its primary application lies in detecting current flow through conductors, enabling precise control and monitoring of power delivery. The transformer's design incorporates a primary winding inserted through a hole in the casting, and a decal arrow indicates polarity for proper installation. Derating is required for higher frequencies and unidirectional operation.
