How to install the Moldova AC power supply so that it can function as a protection switch?(2)
power source is realized through the power transfer switch.
Modern UPS generally adopts pulse width modulation technology and modern power electronic devices such as power MOSFET, IGBT, etc., the noise of power supply can be reduced, and the efficiency and reliability can be improved. The introduction of microprocessor software and hardware technology can realize intelligent management of UPS, remote maintenance and remote diagnosis.
The maximum capacity of the online UPS can be made to 600kVA. The development of ultra-small UPS is also very rapid, and there are already 0.5kVA, lVA, 2kVA, 3kVA and other products of various specifications.
Moldova 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 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.
