Description
The Power Test AC Series Dynamometer is designed and manufactured using a powerful yet simple design solution; unlike typical Water Brake or Eddy Current Dynos; they have the ability to apply power to the engine as well as absorb power from the connected shaft. This gives AC Dynamometers additional functionality , such as simulating the forces on an engine while a vehicle is rolling downhill, or allowing the dynamometer to crank an engine, which eliminates the need for an engine-mounted air or electric starter.
AC Dynamometers also eliminate the need for cooling media (water systems) to remove the power absorbed from a engine. Power produced by the engine, while it is operating in LOAD mode, may be dissipated using an air-cooled resistive load bank, or returned to the electrical grid – via an AC regenerative drive. Where permitted, the operator of an AC Dynamometer can receive payment (or credit) from the utility for the returned power via net metering.
Features
- Full 4-Quadrant Variable Frequency Drive for bi-directional, absorbing or motoring operation.
- High-Precision inline torque meter measures direct flywheel torque.
- High-torque low-inertia machines.
Benefits
- “Green” energy technology returns power absorbed from the unit under test.
- Eliminate dynamometer cooling media requirements.
- Continuous dynamometer motoring capability eliminates the need for engine starters or cranking motors.
