How to install the The Dominican Republic AC power supply so that it can function as a protection switch?(2)

Uninterruptible Power Supply (UPS)
An uninterruptible power supply (UPS) is a highly reliable and high-performance power supply necessary for computers, communication systems and occasions that require uninterrupted supply. The AC mains input is converted into DC through the rectifier, part of the energy is charged to the battery pack, and the other part of the energy is transformed into AC through the inverter, and sent to the load through the transfer switch. In order to still provide energy to the load when the inverter fails, another backup

The Dominican Republic The three-phase AC power intelligent protector has major electrical fault protection functions such as overvoltage, low voltage, neutral wire disconnection, short circuit, phase loss/opening, etc., and has fault identification, fault indication, voltage before closing, neutral live wire reverse connection, Zero line disconnection, phase loss/phase failure detection, remote monitoring, online parameter modification and software upgrade functions.

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 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.
