FAQ |
|---|
| Q1: What is the main advantage of using this over a standard Variable Frequency Drive (VFD) for motor testing? |
| A: This supply provides a clean, pure sine wave output with precise regulation and wide adjustability, ideal for measuring true motor performance without the harmonic distortion introduced by a VFD's PWM output. It acts as a perfect grid simulator. |
| Q2: Can it test single-phase motors as well? |
| A: While designed for three-phase loads, it can be configured to supply one phase (L-N) for testing larger single-phase motors, utilizing its robust current capability. |
| Q3: How do I simulate different line voltages (e.g., 208V or 600V) for motors designed for those standards? |
| A: The output voltage is continuously adjustable from 0V. You can set the L-L voltage to match the motor's nameplate rating (e.g., 208V or 480V). For voltages beyond 520V, a custom output transformer option is available. |
| Q4: Is it suitable for testing motors with attached loads (like a pump or gearbox)? |
| A: Absolutely. Its high overload capacity makes it ideal for testing the motor while it is coupled to its actual mechanical load, simulating real startup and run conditions. |
| Q5: Can the output frequency go above 60Hz or 50Hz to test overspeed conditions? |
| A: Yes, the frequency is adjustable up to 400Hz, allowing you to test motor performance, bearing stability, and insulation at speeds above the base frequency (overspeed testing). |
