The high-frequency machine uses the microprocessor (CPU chip) as the processing control center. It burns complicated hardware analog circuits into the microprocessor and controls the operation of the UPS in the form of software programs. Therefore,Charger the volume is greatly reduced, the weight is greatly reduced, Charger the manufacturing cost is low, and the price is relatively low.
The inverter frequency of the high-frequency machine is generally above 20KHZ,Charger but the high-frequency machine has poor tolerance under harsh power grid and environmental conditions, and is more suitable for environments where the power grid is relatively stable, with less dust, and suitable temperature and humidity.
Comparison of high-frequency machine and industrial frequency machine: small size,Charger light weight, high operating efficiency (low operating cost), low noise, suitable for office places,Charger high cost performance (low price under the same power), and impact on space and environment Because the transformer of the power frequency machine isolates the mains power from the load, the power frequency machine can provide safer and more reliable protection than the high frequency machine in the harsh environment of the city power. In some occasions,Charger such as medical treatment, the charger is required. Isolation device. Therefore, Charger for industrial, medical, transportation and other applications, industrial frequency machines are a better choice.
