Performance characteristics of high frequency pure sine wave inverter？

l This series refers to the intelligent dedicated inverter power supply and employs intelligent microcomputer CPU control technology and advanced control theory as well mature and stable high-frequency inversion mode in order to rapidly respond to the external environment change and constantly provide the high-quality AC output in a real-time manner.

l Such inverter employs advanced PWM+SPWM pulse width modulation technology to realize output soft start, and the output thereof is the pure sine wave with stable frequency and voltage, filtered noise and low distortion factor.

l Different from other false isolation mode, the advanced DC-AC electric isolation technology can really realize the completely electric isolation of DC and AC in all circuits and accordingly meet the isolation requirements of all application systems as well as eliminate all possible mutual interferences.   

l This product has startup self-inspection function, strong loading capability and good load compatibility; the built-in by-pass switch has improved the continuity and reliability of the inverter power supply.

l This product also has direct startup function by mains and allows the users to provide power supply to the load through the by-pass mains when there is no DC input; meanwhile, it also allows to cut off DC under startup status and to automatically switch to the mains by-pass, without influencing the power supply for the load while facilitating the maintenance replacement of the storage battery.  

l This product also has intelligent unattended operation function, namely: after the output is cut off due to too high or too low DC voltage, mains failure, etc., the power supply can automatically recover the output when the DC voltage or the mains returns to normal condition. Therefore, this product is especially suitable for the unattended communication base.

l This product has perfect safety protection functions, such as DC input inverse connection prevention and DC input buffering protection and other comprehensive protection measures for overvoltage, overload, short circuit, over-temperature and inverter fault.

l Due to the adoption of the advanced backward noise suppression techniques, this product does not mutually intervene with the communication equipment sharing the DC cabinet. The AC input terminal employs multiple filtering to eliminate the interference of the utility power grid in order to meet the requirements of the application system for AC-dominated power supply.

l This product can flexibly set AC-dominated power supply and DC-dominated power supply (such power supply form can be switched through LCD panel or communication background software):

? When there is mains, AC-dominated inverter power supply is under mains output mode; in case of mains fault, AC inverter power supply automatically switches to inverter output.

? DC-dominated inverter power supply is under inverter output mode during normal operation, and automatically switches to mains by-pass output during the occurrence of DC input fault.

l This product also has the function of LED+LCD status display, alarm signal display and alarm recording, and is provided with 128*64 lattice screen as the perfect humanized man-machine interface with blue background and white subtitles.

l This product has 5 groups of passive dry contacts respectively for DC input fault, AC input fault, overload information, by-pass information and output fault.

l This product is also provided with completely independent RS232 and RS485 communication interfaces, and supports real-time data communication function, and can use the monitoring software to monitor and control the working condition of the inverter power supply in a real-time manner.

l This product supports built-in TCP/IP communication to realize remote network monitoring and management of the inverter power supply.(Optional)

l This product supports built-in SNMP communication to realize the interconnecting function of the inverter power supply and attain the objective of network monitoring and management.(Optional)
