  • Page 3 28/06/2013 7CH4Q107_E_4 INTRODUCTION The controller 7CH4Q107 is a 4 quadrant chopper for PMDC motors powered by battery 24/36V for traction applications. The chopper is equipped with a powerful microprocessor for digital control of the speed, current regulation and failures of the motor ; an efficient diagnostics of the failures and wrong wiring connections, programmability of the main parameters .

    28/06/2013 7CH4Q107_E_4 INSTALLATION fig.2 Locate the chopper in a place protected against mechanical abuse, water and dirty. Fix it with all the screws on a metal surface (aluminum if possible) to reduce the heath and so for longer period of work. If during the standard operations the thermal protection is activated very often an additional heath-sink or fan is requested to assure longer periods of work.
