4-Quadrant Regenerative DC Dynamometer Systems

Use the Same Dynamometer Control for DC, AC, Eddy Current and Water Brake

DyneSystems DC motoring dynamometer system with drive and regenerative DC dynamometers in 35, 50 and 75 horsepowerDyneSystems DC motoring dyno system with wall mounted 1-100hp drive and 35, 50 and 75 hp Regenerative DC Dynamometers

DyneSystems Static DC 4-Quadrant Dynamometer Controls utilize either the Inter-Loc V or the Dyn-Loc IV digital dyno controllers to control RPM (speed) and torque. Using the same control for DC, AC, EC and WB dynamometers allows more flexibility within a test cell's equipment design, reduces space requirements and simplifies automation.

Throttle Control

DyneSystems DC Systems also provide for easy integration of either the DTC-1 Digital Throttle Controller or the Inter-Loc V Throttle Control Module.

Field Control

Field control in a DC dyno usually receives little consideration. DyneSystems' design includes a wide-band 4SCR regenerative, current source field amplifier with bidirectional forcing for fast field control when operating above dynamometer base speed. It also insures that armature voltage will be limited to the dyno-rated value.

Safe Energy Recovery

DyneSystems DC drives are regenerative, and allow safe return of generated power to the electrical grid.
