I have a Vibration tester to test electronic PCB's and small assembled units. The shaker can handle 100 volt @ 20 amp RMS. Correct 2 KW. It only has a 0.3 ohms DC coil and most audio amps will normally only work down to 2 ohms.
The frequency range is from 5hz to 2k and I was wondering if a servo drive would work with some mods. I could use an analog to pulse conversion unit to drive it.
Thanks Wallace
