current sensing transformers document 132 specifications subject to change without notice. document 132 revised 04/05/04 these low cost coilcraft current sensing transformers are designed for use at 20 khz to 50 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 10 volts per ampere output. coilcraft current sensing transformers are designed to comply with creepage, clearance, insulation, and hi-pot requirements of iec 380 and iec 435, and with ul and csa specifications. applications include feedback control, overload sensing, detecting load drop or shutdown, and proportional output. coilcraft designer?s kit p203 contains the three stan- dard current sensing transformers, sensor-only versions of each, plus two 50/60hz current sensors. to order, contact coilcraft or visit http://order.coilcraft.com. sensed sensitivty terminating part inductance current vout i in resistance 1 number turns (mh) max (a) (volts) (a) (ohms) cs4050v-01 50 5 10 1 1 50 cs4100v-01 100 20 24 1 1 100 CS4200V-01 200 80 35 1 1 200 coilcraft cs-4xxxv 906 xxx sense current max 0.75 19,05 0.105/0.150 2,67/3,81 0.77 19,56 0.03 0,76 0.60 0.01 15,24 0,25 0.40 0.01 10,16 0,25 0.40 0.01 10,16 0,25 lead diameters 1 & 4: 0.041 / 2 & 3: 0.052 / 1,041 1,321 4 1 2 3 max 0.57 14,48 weight: 8.8 ? 9.3 g 1. varying terminating resistance increases or decreases output voltage/ampere in conductor. effect is essentially linear over a restricted operating range. frequency response is also affected by varying terminating resistance. 2. operating temperature range ?40c to +85c. 3. electrical specifications at 25c. 3 sec pri 2 1 4 terminating resistor v out current i in
