Q & A:

 

1. Q: What types of current can be measured?

     A: DC, AC(up to several KHz) , PWM

 

2. Q: What is the reading out of this sensor?

     A: DC voltage,the range is from 0 - Vcc 

         * Vcc : 4.5 V -- 6 V

 

3. Q: How do I convert the voltage reading to the unknown current value?

     A: Formula: Unknown Current (A) = (V1-V0) / CF

          e.g. V0 = 2.5 V , CF = 0.0224

          V1 is the volt reading @ unknown current    

             

         Example 1:

         V1=3.5 V

         Unknown Current (A) = (3.5-2.5) / 0.0224 = 44.64 A

         

         Example 2:

         V1=2.0 V

         Unknown Current (A) = (2.0-2.5) / 0.0224 = -22.32 A

 

4. Q: What are V0 and CF?

     A: V0 is the output voltage at 0 Amp

          CF is increase of volt reading when the current increase 1 Amp

       *  All sensors will be shipped along with calibrated values of V0 and CF   

        

5. Q: How can I measure V0 and CF?

     A: To measure V0:

          Power on the sensor and read the output voltage while no current is 

          applied. This voltage is V0.

          To measure CF:

          While applying some current(e.g. 20 amp)  to sensor (passes through 

          the toroid core), read the output  voltage V1. The CF can be calculated using 

          the formula: CF=(V1-V0) / 20
