Current Transducer


Thread Starter

I'm trying to use a Temposonics feedback device on a hydraulic servo axis. This device has the ability direct drive the hydraulic servo valve. Problem is that its capability is limited to +/- 50mA and I need +/- 400mA for this valve. Anybody know of a low latency current transducer that would do the job?

What voltages are you running? Is it less than 24V? How accurate do you need? 5%, 1% .1% ?? How much can you spend? It may be a relatively simple transistor and op-amp or high output op-amp circuit. In this case, the latency would be less than 1 microsecond. How much latency can you tolerate? Kip [email protected]

National Semi, Burr-Brown and others sell current boosters that should work for this. I don't really understand your application, but the buffers should have adequate BW and phase margin. Regards cww
