Part Number: AMC1100
My requirement is to monitor the 120V AC power supply when the load(1500Watt Heater) is connected and maintained the power level when there is variation in input range(110 VAC to 125VAC). I am trying to build a circuit which can deliver below result:
Input current Delta = 1.63 Amp(Rms)
Vout= 0-5VAC (pk-pk)
I thought of using an AMC1100 amplifier. can anyone suggest which approach would meet my requirement?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Tom Hendrick:
sorry for the delayed response, the application would be to use this in Toaster and Temp Probe ovens, The wattage of the heaters in this type of product need monitoring on the 120VAC/230VAC line. Basically, need power leveling when there is a variation in the 120/230VAC power supply. the variation could be +/-10%.
Currently, this feature is not yet implemented in the any of the product so looking for a cost effective solution.
I have come up with some approaches:
1. Using Current transformer:
It seems very bulky and fairly expensive.This would be appropriate for my requirement since I am sensing high current(5-10Amp)
2. Hall Effect current sensor:
It's easy to use but expensive.
3. Isolation Amplifier: (AMC1100)
expensive and complex, but it seems the desired accuracy can be achieved using this method.
4. Using a Step-Down transformer and drop the voltage to the desired level. it's easy to use but the problem with this to get the right transformer.
could you please suggest the best approach for this kind of application with the low-cost design.
In reply to Rajesh kumar:
I will talk with the local staff and see if I can get someone to help you with this request.
Thanks for the reply, Please get back to me as early as possible.
Yes, he did, Based on my requirement he suggested using AMC1100 solution.
Thanks for confirming me again.
