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

(9) For the high-voltage module power supply, do not touch the high-voltage dangerous area during use and within 10 minutes after the power outage.
(10) Purchasing principle of module power supply: Generally, switching power supply should be selected for larger power, and linear power supply should be selected for smaller power.
(11) The module power supply cannot be forcibly dismantled, and it will be damaged if it is forcibly dismantled.

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 Marine boost/buck voltage 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 Costa Rica   Marine boost/buck voltage power supply voltage, neutral line disconnection, phase loss / disconnection, etc., and cut off the Marine boost/buck voltage 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.

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