How to install the German AC power supply so that it can function as a protection switch?(3)

The three-phase AC power intelligent protector has developed and created the function of "fault detection before closing", which has greatly improved its performance and reliability. The three-phase AC power intelligent protector detects the LED advertising screen power supply voltage, the reverse connection of the neutral line, the disconnection of the neutral line, and the lack of phase/phase failure through the single-chip microcomputer before the main switch is closed.

During operation, it can track and detect the German  LED advertising screen power supply voltage, neutral line disconnection, phase loss / disconnection, etc., and cut off the LED advertising screen power supply in time when a fault occurs, making it safer and safer to use electricity. More reliable; at the same time, through a set of attached indicator lights, it shows the fault situation, which provides convenience for line maintenance.

In the early 1980s, the research on the distributed high frequency switching power supply system basically focused on the research of the converter parallel technology. In the mid-to-late 1980s, with the rapid development of high-frequency power conversion technology, various converter topologies appeared one after another. Combined with large-scale integrated circuit and power component technology, it became possible to integrate small and medium power devices, thereby rapidly Promote the development of distributed high-frequency switching power supply system research. Since the late 1980s, this direction has become a research hotspot in the international power electronics field.

German It can be widely used in electrical equipment protection stations, meteorological telemetry stations, energy pipeline telemetry stations, petroleum Exploration, automatic pumping and other places.
