How to install the Jamaica 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 Jamaica 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.
●Low technical requirements. Modular power supplies are typically equipped with standardized front ends, highly integrated power modules and other components, thus simplifying power supply design.
●The module power supply shell has a three-in-one structure of heat sink, radiator and shell, which realizes the conduction cooling mode of the module power supply and makes the temperature value of the power supply approach the minimum value. At the same time, the normative packaging of the module power supply is given.
Jamaica It can be widely used in electrical equipment protection stations, meteorological telemetry stations, energy pipeline telemetry stations, petroleum Exploration, automatic pumping and other places.
