How to install the Vatican 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 24V input 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.

For the ADJ output pin, it is divided into input side adjustment and output side adjustment. The output side is adjusted in the same way as the TRIM pin. The input side adjustment can only increase the output voltage. At this time, one end of the potentiometer is connected to the center, and the other end is connected to the ground of the input end.

During operation, it can track and detect the Vatican   24V input power supply voltage, neutral line disconnection, phase loss / disconnection, etc., and cut off the 24V input 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.

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