How to install the Portugal 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 48V 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.

(1) After opening the package, it is necessary to carefully check whether the identification of each terminal is in line with the instructions that are brought along with it, and whether it is in line with the requirements of the order contract. If it does not match, you should immediately contact the production or sales unit to discuss how to deal with it.
(2) As the first step of installation, the metal casing of the module power supply must be grounded reliably to ensure safety, but the casing should not be connected to the zero line by mistake.

During operation, it can track and detect the Portugal   48V input power supply voltage, neutral line disconnection, phase loss / disconnection, etc., and cut off the 48V 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.

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