I need equipment to monitor amps and temperature of DC motors.
If a Pico current clamp is across a wire that has 15 kHz of PWM will this throw the reading off? The PWM will vary from 0 to 100%, the zero and 100% I am sure is covered.
I will also need to measure motor casing temperatures; however the place I need to monitor the most is right where the magnetic energy is the strongest. What would this do to something like a "K" style thermocouple?
We are talking 5 to 1000 amps depending on motor and system. I know shunts work fairly well in this situation but are not a mobile as a Pico amp clamp would be. I am looking at the PP253.
