I am looking for an isolated current sensor that is isolated and capable of 600 amps DC. Either something like Allegro's solder-in sensors or a contactless sensor like those from Amploc. I'd use one of those two except for the 200A and 300A limits. I'm hoping not to have to do a current divider, multiple sensors, or any other kludge. Anyone using or know of something off the shelf that'll work for me?
