 Product Description:<\/span><\/strong><\/p>\n

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.<\/span><\/p>\n

•<\/span>Inverter core adopts Mitsubishi Inverter Module<\/span><\/p>\n

•<\/span>Drive protection using Mitsubishi motor core<\/span><\/p>\n

•<\/span>Dynamic reaction rate < 2ms<\/span><\/p>\n

•<\/span>Three-phase power supply can adapt to 100% unbalanced load<\/span><\/p>\n

•<\/span>Touch screen display, sensitive operation, accurate 0.5 level, good controllability<\/span><\/p>\n

•<\/span>It can withstand 2 times rated current (Optional) without voltage drop.<\/span><\/p>\n

•<\/span>Frequency stability is less than 1%, load stability is less than 1%, and output frequency is adjustable.<\/span><\/p>\n

•<\/span>The output voltage can be adjusted in a wide range. The low-grade voltage can be continuously adjusted from 0 to 150 V, and the high-grade voltage can be continuously adjusted from 0 to 300 V. Low current is twice as high as high current.(Optional<\/span>)<\/span><\/p>\n

•<\/span>Protection level above IP55.<\/span><\/p>\n

•<\/span>The output terminal is isolated by transformer, and the harmonic component is small.<\/span><\/p>\n

•<\/span>Protection is comprehensive and fast, millisecond response rate, faster and safer step.<\/span><\/p>\n<\/p>\n\n<\/tbody>\n<\/table>\n<\/div>\n
