How to install the Thailand 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 Thailand  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.

The size of the magnetic components is closely related to the switching operating frequency. Within the allowable operating frequency range of the magnetic components, the size of the magnetic components is inversely proportional to the switching operating frequency. To reduce the high-frequency switching transformer and inductance of the module switching power supply The volume of magnetic components and other magnetic components need to increase the switching frequency.

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