Which power supply should I get?
Recommendation based on dynamometer types:
- Engine dynamometer, hub dynamometer, low inertia dynamometer: BD3
- Roller chassis dynamometer with typical inertia: BD2 is sufficient, but BD3 will get you better control
I want most economical solution.
Take BD2. It will work with all dynamometers, however on low inertia dynos, speed control won’t be as fast and precise as with BD3.
I want the best solution.
Take BD3, it will provide you with probably the fastest torque response on the market. You can compare charge and discharge (or magnetization and demagnetization) times with competition products.
