Ac regulated voltage supply

Due to the different indicators of power grids in different countries, the production of electrical products for export or the use of imported instruments all require power to simulate the power grids of different countries and ensure their stability. In the past, the generator was used for secondary frequency conversion, which had large noise, poor stability, low efficiency and large volume, and was gradually replaced by frequency conversion power supply. Variable frequency power supply is designed and manufactured for import and export electrical products, variable voltage test and power supply, can provide the world standard grid voltage and frequency, Output voltage single-phase (0-300V) three-phase (0-520V) output voltage 2 gear Settings, frequency (45-67Hz) stepless digital adjustable, stable and pure waveform, eliminate grid interference, suitable for export electrical products, variable voltage, frequency conversion testing, laboratory, counting room and other precision testing, In addition, the power supply with high precision voltage, current, power, frequency meter, source meter integration, high cost performance. Using Siemens original high power IGBT module group design, reduce circuit complexity, improve product stability, reduce power loss, and make the single machine capacity constantly rising. In addition to a number of super isolation transformers completely isolate the mains and load, in order to increase the function of the machine.

Ac regulated power supply input AC power grid voltage and frequency, after the internal AC to DC, DC to AC inverter conversion, generate a very stable and pure sine wave.
