There phase input and three phase output high-frequency Online UPS

There phase input and three phase output high frequency Online UPS

U330/H series fully embodies the essence of the cutting-edge technology of Yunzheng network, the whole UPS adopts advanced DSP digital control technology and UHF control technology, to create a small size, light weight, high efficiency; The zero conversion design and pure sine wave output technology ensure that the user device is suitable for a variety of devices. A unique AC-DC conversion circuit is used to detect the output current and output voltage of the mains, and through the high-frequency pulse width modulator, the current waveform of the input power supply is in phase with the voltage waveform, so as to achieve a high input power factor greater than 95%. Under normal conditions, the mains obtains DC BUS voltage through the AC-DC circuit, and then converts the DC BUS into AC output through the inverter. The high frequency Online UPS used for all loads is the pure sine wave power supply that is stabilized by voltage and frequency and filters noise. Using excellent IGBT as a power conversion element, due to the high frequency switching characteristics of IBGT, the working frequency of UPS inverter can reach 40KHz, the working efficiency of the inverter is improved, and the efficiency of the UPS is improved, and the inverter frequency is increased, and the noise of the inverter is also reduced. In this way, the YZ-U330H series high frequency Online UPS placed directly in the computer room will not affect your work. Yunzheng high frequency Online UPS YZ-U330H series UPS through RS232 communication interface with Yunzheng monitoring software, UPS and network server are connected as one, to provide power status at any time; And realize timing self-check, automatic storage, automatic timing switch and record power status and other intelligent functions, to achieve human-machine communication zero distance. When the mains is interrupted, the Online UPSnotifies the server that it is ready to shut down, automatically saves all data, and runs the normal shutdown command. This ensures data security even in an unoperated network environment.
