FAQ |
|---|
| Q1: Why is 400Hz used in aerospace applications? |
| A: 400Hz allows for the use of smaller, lighter, and more efficient motors and transformers in aircraft, which is critical for weight savings. Our source replicates this on-ground for testing. |
| Q2: Can this power source simulate abnormal conditions like surges or sags? |
| A: While primarily a precision source, its adjustable voltage function allows you to set specific output levels to simulate steady-state under-voltage or over-voltage conditions for testing. |
| Q3: Is it suitable for testing equipment with high inrush currents? |
| A: The unit features a strong overload capacity (typically 125-150%). It is designed to handle the momentary inrush currents of motors and transformers commonly encountered in 400Hz systems. |
| Q4: How does this differ from a Variable Frequency Drive (VFD)? |
| A: A VFD is for motor control and often outputs a non-sinusoidal waveform. This is a Precision AC Power Source designed to output a clean, pure sine wave with high stability and low distortion, suitable for powering sensitive electronics, not just motors. |
| Q5: Can the output frequency be set to other values besides 400Hz? |
| A: Yes, many models are field-adjustable across a range (e.g., 300-500Hz) to support testing of equipment designed for similar but non-standard high frequencies. |
