The AMP-0039C is a digital version of the legacy AMP-0039 and is suitable as a drop in replacement. The AMP-0039C is made by Glentek and will match the performance of the analog AMP-0039. Many of the thru hole components have been replaced with surface mount components to increase product reliability. This amplifier can be used with AC axis motors with 5000 encoders.
