TRM has designed a range of high quality drives that we manufacture in-house. TRM's drives work in current mode (torque mode) where the input command voltage controls the output current (torque).  The drive will adjust duty cycle to maintain the commanded current.  This is the most common mode when an external controller is used which can close the velocity and/or position loops.  These drives are self contained with a heavy-duty heatsink and a quick and easy mounting system.

*Whilst the built in heatsink is adequate for most uses, under certain situations it is recommended to use a cooling fan and/or fix to a larger heatsink. If you are in any doubt please contact us for further advice on your application.
