Current Sense Transformers
These low cost Coilcraft current sensing transformers are designed for use up to 1 MHz. They incorporate the current and sense windings in one small, encapsulated package requiring minimum board space.
Coilcraft current sensing transformers are designed to meet UL/CSA/IEC 60950 Reinforced Insulation specification and provide 3 mm creepage/clearance between primary and secondary windings. Winding to winding isolation (hipot) is 3750 Vrms, tested for one minute.
Applications include feedback control, overload sensing, detecting load drop or shutdown, and proportional output.
Coilcraft Designer’s Kit P403 contains the three standard current sensing transformers, sensor-only versions of each, plus two 50/60Hz current sensors.
