Testing Voltage (1 minute): Line to line 1500 V DC

Line to Ground 1500V AC/2500V DC

Operating frequency: 50/60 Hz

Range Of Temperature: -25-85℃

Insulation Resistance: Line to ground (up to 300A) ≥ 1500MΩ


Three-phase output filter

Based on different operating frequency, clients can reasonably choose the magnetic materials (such as silicon steel sheet, ferrite, amorphous iron core and magnetic powder core) as the raw material of this product.           

The excellent performance of this equipment is due to the foil winding structure, low DC resistance, strong resistance to electromagnetic force and good overload ability in short time. F and above class composite insulating materials are used to ensure the reliable performance of the output AC reactor under harsh working conditions; The advantages of the design includes low magnetic flux density, high linearity and good overload capacity. Moreover, the cooperation of the design and the vacuum pressure impregnation process ensures the low noise of the product.
