Description

The system adopts online double transform structure design, completely eliminate the disturbs on the electricity net; AC/DC input with harmonic wave suppresser, stopping the harmonic wave polluting the electricity net, DC/AC convertor adopts SPWM pulse width adjustment technique, IGBT power module, and output isolation transformer. Then the ups will output pure sine wave power supply which has stable frequency and voltage , no noise and disturb. This series of UPS can satisfy many application environment because of the high load ability, good compatibility, large range of city input voltage and frequency, output no switch time and excellent generator with matching compatibility. Perfect protective circuit, which improve the stability and reliability. Features: ●Adopt numeric control technique and perfect protective circuit, good stability ●The power parts adopt imported original IGBT module design. ●Adopt double transform technique and static state electron side road technique ●Large range of the voltage and frequency, reducing the chance of battery discharging, and prolong the life of the battery ●Adopt the advanced constant current and voltage automatic transform charge technique and float full technique, fully activate the battery ●Well cold boot function, it can make cold boot with full load if there is not the electricity, and can satisfy the emergent requirement for the clients. ●The output realizes precise zero phase synchronization with the electricity net, improve the reliability of the static state electron side circuit. ● Human-machine interface design, adopt Chinese LCD liquid crystal display, the running state of the UPS is clear at a glance, realizing zero distance communication between the human and the machine. ●The content of the LCD: The model, input/output voltage, frequency, load capacity, the capacity of the battery, the temperature inside, running state, working ways and the malfunction.
