Brief introduction of variable frequency power supply:
This variable frequency power (ACPOWERSOURCE)It is a kind of precision that transforms the city electricity through the power conversion circuit to the needed voltage and the frequencyPower Supply.Because the power grid indicators are not uniform, the production and export products need to simulate the power grid situation of different countriesTest all kinds of export electrical products. The generator was used two times in the pastFrequency conversion, but large power consumption, large noise, poor stability. Variable frequency power supply can provide the world standard voltage and frequency of the grid. The output voltage and frequency are stepless digital adjustable, which is suitable for testing the voltage and frequency of the export electrical products. Variable frequency power supply can also be used as the power supply for imported 60HZ equipment

Performance characteristics of variable frequency power supply:
This variable frequency power supply with sinusoidal pulse width modulationPWM Design, imported MITSUBISHI1GBT promote.. The reaction is fast and correct100% In addition to loadThe time of loading and stabilizing reaction is in2ms Within. Waveform purity,High frequency stabilityNo interference magnetic waveEMI 、 EMC )。Variable frequency power supply is not only the best power supply for R & D and laboratory, metering room, but also the power supplyEM/EMC/ Standard for safety testingPower Supply。
This power inverter with load adaptability, high efficiency, good stability, quality good output waveform, simple operation, small volume and light weight. For different types of power sources around the world, users can not only simulate voltage and frequency around the world40 ~ 70Hz For testing applications, which are made according to the national military standardIntermediate frequency power supply can also support 400Hz, 1000HZ frequency of national defense military detection, avionics and navigation, communications and other application equipment.
◇ Our company according to customer requirements to develop alarm indicator function, can be rightThe working condition of the frequency conversion power supply is accurately positioned, so that the customers can accurately evaluate the use environment of the variable frequency power supply.
