Product Description


The main function of this series of variable frequency power supply is to transform the mains power into a power supply of the required voltage and frequency through the power conversion circuit. Its main feature is to provide pure and reliable sine wave power output, low harmonic distortion, high stability of frequency and stabilization rate. It can simulate the output characteristics of different voltages and frequencies from all over the world, covering the needs of the entire industry, and fully meet the engineer’s product testing, life, over-voltage/under-voltage simulation test, imported equipment and production line power supply in design and development, production line testing and quality assurance And other applications. In addition, it can also support 400Hz aerospace and military equipment.



Features


1.Inverter core adopts original Mitsubishi inverter module

2.Drive protection adopts original Japanese Mitsubishi movement.

3.Dynamic response speed <2ms.

4.Three-phase power supply can adapt to 100% unbalanced load.

5.Touch screen display, sensitive operation, accurate 0.5 level, good controllability.

6.Super load capacity, can withstand 2 times the rated current (customizable), and will not cause voltage drop.

7.Frequency stability ≤1%, load stability ≤1%, output frequency is adjustable.

8.Wide output voltage adjustment range, low-grade voltage 0-150V continuously adjustable, high-grade voltage 0-300V continuously adjustable. Low-grade current is 2 times of high-grade current (customizable).

9.Protection level above IP55.

10.The output terminal adopts the transformer to isolate the output, the harmonic component is small.

11Comprehensive and quick protection, millisecond response rate, faster and safer.
