1, the definition of different:
High-frequency machine: the use of high-frequency switching technology, high-frequency switching components instead of rectifiers and inverters in the frequency transformer UPS, commonly known as high-frequency machine, high-frequency machine, high-frequency machine, small size, high efficiency.
Industrial frequency machine: the use of industrial frequency transformer as the rectifier and inverter components of the UPS is commonly known as industrial frequency machine, the main characteristics of the main power components are stable and reliable, overload capacity and anti-shock anti-jamming ability, strong with load capacity.
2, the principle of different:
Industrial frequency machine single-input single-output UPS breaks through the technical bottleneck in the UPS industry, to the advanced digital circuit system instead of the traditional analog circuit, to achieve extraordinary innovation. In digital circuit mode, high-speed microcontrollers and programmable logic devices provide more perfect circuit control, parameter setting and operation management, and more powerful self-test and self-detection functions.
The high-frequency high current of the high-frequency machine flows to the heating coil which is wound into a ring or other shapes. This produces a strong magnetic beam with instantaneous change of polarity inside the coil. When a heated object such as a metal is placed inside the coil, the magnetic beam passes through the entire heated object, and a large eddy current is generated inside the heated object in the direction opposite to the heating current.
3, different overload capacity:
High-frequency machine overload capacity in general; industrial frequency machine overload capacity is stronger.
4, the input PF value is different:
High-frequency machine input PF value of 0.99; industrial frequency machine input PF value of 0.9.
5, the power density is different:
High-frequency machine power density is high; industrial frequency machine power density is low.
6, the volume is different:
High-frequency machine's volume is small; industrial frequency machine's volume is large.
