UPS(Uninterruptible Power Supply不间断电源)。 一般地说,“电源”是提供电能的装置,这里主要是指电子设备电源。UPS是以电力变流器构成的保证供电连续性的静止型交流不间断电源设备。或者说,UPS是由电力变流器、储能装置(蓄电池)和开关(电子式或机械式)等组合而成的一种电源设备。这种电源设备能在交流输入电源发生故障(如供电中断,电压、频率及波形等不符合要求)时,保证向负载供电的连续性,并且在供电电压、频率和波形等方面改善供电质量,使之保持在规定的范围之
UPS (Uninterruptible Power Supply uninterruptible power supply). In general, “power” is to provide power devices, here mainly refers to the electronic equipment power. UPS is based on the power converter to ensure the continuity of power supply static AC uninterruptible power supply equipment. Or, UPS is a power device composed of power converter, energy storage device (battery) and switch (electronic or mechanical). This kind of power equipment can guarantee the continuity of power supply to the load when the AC input power fails (such as interruption of power supply, voltage, frequency and waveform, etc.), and improve the power supply quality in terms of supply voltage, frequency and waveform, Keep it within the prescribed range
