Product Description:

The main function of this series of variable frequency power supply is to convert the municipal power to the required voltage and frequency through power conversion circuit. Its main characteristics are to provide pure and reliable sinusoidal power output, low harmonic distortion, high stability frequency and voltage stabilization rate. It can simulate the output characteristics of different voltages and frequencies in different parts of the world, covering the needs of the whole industry. It fully meets the needs of engineers in design and development, product line testing and product quality assurance, life, over-high/over-low voltage simulation testing, imported equipment and production line power supply applications. In addition, it can support 400 Hz aerospace and military equipment.

 

3 phase ac power supply
