MCBP Series Variable Frequency Power Supply

The MCBP Series Variable Frequency Power Supply is a precision power source that converts mains power into the required voltage and frequency via power conversion circuits. Developed independently by our company, this high-performance variable frequency power supply outputs various custom voltages and frequencies to meet the power supply and testing needs of electrical products from different countries and regions. It can also serve as a power supply for imported 60Hz equipment, convert single-phase 220V power to three-phase 380V power, and is suitable for applications such as converting three-phase 220V (60Hz) to three-phase 380V (50Hz), or accepting three-phase 380V (35–70Hz) input and outputting 380V (50Hz).
