FJB11C-5K Programmable Variable Frequency Power Supply

Due to the inconsistent power grid indicators in different countries, the production and export of electrical products or the use of imported instruments require power sources to simulate the power grid conditions of different countries and ensure stability In the past, using generators for secondary frequency conversion resulted in high noise, poor stability, low efficiency, and large size, gradually being replaced by variable frequency power supplies. FJB variable frequency power supply is designed and manufactured specifically for the transformation, frequency conversion testing, and power supply of imported and exported electrical products. It can provide standard grid voltages and frequencies from around the world, with output voltages of single-phase (0-300V), three-phase (0-520V), and two gear settings for output voltage. The frequency (45-67Hz) is infinitely variable and the waveform is stable and pure, eliminating grid interference. It is suitable for transformer and frequency conversion testing of exported electrical products, as well as various precision tests in laboratories, metrology rooms, etc. In addition, the power supply comes with high-precision voltage, current, power, and frequency meters, integrating the source and meter, and has a high cost performance ratio Adopting Siemens original high-power IGBT module group design, reducing circuit complexity, improving product stability, reducing power loss, and continuously increasing single machine capacity. In addition, multiple ultra isolation transformers completely isolate the mains and load to increase the overall functionality of the machine.
This power supply inputs the voltage and frequency of the AC power grid, and after internal inversion conversion from AC to DC and DC to AC, it generates a very stable and pure sine wave on its own
