Part Number: AMC1350
Other Parts Discussed in Thread: AMC0386
Hi,
We are using AMC1350 for voltage sensing. Our requirement is to get 0.1 % accuracy in sensing the voltage. We have to chose resistors such that we get 0.1 % accuracy and power loss of each resistor should be very less.
While checking the datasheet of AMC1350 , it is mentioned that for 230 Vrms 100 uA is the recommended current through the resistor divider network. But if we use 100 uA power loss will be less but it is affecting the accuracy. By increasing current only we will be able to achieve the 0.1 % accuracy.
This data is given in datasheet. Here current of 10 mA is mentioned. Is this the maximum amount of current through the resistor divider network ?
Inorder to get 0.1 % accuracy and very low power loss at each resistor what should be the value of current that we have to consider in the resistor divider network ?
The above is the current schematics , the current value considered is less than 100 uA. But there is no accuracy. Sensing is not proper.
Can you suggest the value of current need to be taken while designing the circuit for 0.1 % accuracy ?
