Current Sensing Transformers Document 132 Document 132 Revised 03/20/07 These low cost Coilcraft current sensing transformers are designed for use up to 100 kHz. They incorporate the current and sense windings in one small, encapsu- lated package requiring minimum board space. Varying the terminating resistance allows sensitivities of 1 to 100 Volts output per Ampere input. Coilcraft current sensing transformers are designed to provide 6 mm creepage/clearance between primary and secondary windings Applications include feedback control, overload sens- ing, detecting load drop or shutdown, and proportional output. Coilcraft Designer’s Kit P403 contains the three stan- dard current sensing transformers, sensor-only versions of each, plus two 50/60Hz current sensors.

Inductance is for the secondary, measured at 15.75 kHz, 1 Vrms. 2. Square wave response deteriorates above and below this frequency. 3. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT = Vout × Nsec / Iin 4. Operating temperature range –40°C to +85°C. 5. Electrical specifications at 25°C. SecPri 2 1 RT VoutI in Typical Circuit
