What is the difference between industrial frequency and high frequency machines?

1. Different definitions:

High-frequency machine: UPS that uses high-frequency switching technology to replace the power frequency transformer in the rectifier and inverter with high-frequency switching components, commonly known as high-frequency machine. Frequency machine, high frequency machine is small in size and high in efficiency.

Power frequency machine: A UPS that uses power frequency transformers as rectifier and inverter components is commonly known as power frequency machine. Its main features are stable and reliable main power components, strong overload capacity, impact resistance and interference resistance, and Strong load capacity.

2. The principles are different:

The single-input single-output UPS with industrial frequency machine breaks through the technical bottleneck of the UPS industry, replacing the traditional analog circuit with an advanced digital circuit system, realizing Extraordinary innovation. In the digital circuit mode, high-speed microcontrollers and programmable logic devices provide more perfect circuit control, parameter setting and operation management, and the self-test and self-detection functions are more powerful.

The high-frequency and large current of the high-frequency machine flows to the heating coil that is wound into a ring or other shapes. As a result, a strong magnetic beam with an instantaneous change in polarity is generated in the coil. When a heated object such as a metal is placed in the coil, the magnetic beam will penetrate the entire heated object, and a magnetic field will be generated inside the heated object in the opposite direction to the heating current. Correspondingly large eddy current.

3. Different overload capabilities:

High-frequency machines have average overload capabilities; industrial frequency machines have stronger overload capabilities.

4. The input PF values ??are different:

The input PF value of the high-frequency machine is 0.99; the input PF value of the industrial frequency machine is 0.9.

5. Different power densities:

The power density of high-frequency machines is high; the power density of industrial frequency machines is low.

6. Different sizes:

The high-frequency machine is small in size; the industrial frequency machine is large in size.
