Description

KD-Series low frequency online UPS is a high quality well-designed intelligent low frequency online UPSfor the safe protection of computer networks and sophisticated electronic equipment, electrical equipment at complex network environment. Adopting online double conversion technology, zero interrupt conversion, can completely eliminate all kinds of network interference and failure in providing clean power for the load to ensure the load equipment run efficiently. AC / DC input with harmonic suppressors, so that UPS have no harmonic pollution to the electricity grid; DC / AC inverter uses international advanced SPWM pulse width modulation technology, IGBT power module and the output isolation transformer so that UPS can output  stable pure sine wave power; while with ultra-wide input voltage range and voltage and frequency stabilization function,  strong load capacity, can be compatible with the generator etc. ,  to meet the needs of the load equipment protection in complex grid environment

Technical merits:

●Adopting double conversion technology and the perfect static electronic bypass technology, realizing real zero     interrupt conversion, the user equipment can run reliably in any complex power grid environment.

●Intelligent digital control technology and improved protection, stability and reliability.

   All IGBT power devices using the imported famous brands, have greater impact resistance          and overload capacity.

●Advanced automatic constant voltage constant current charging technology and float charging technology to realize   the maximum activation of the battery

●Ultra wide input voltage and frequency stabilization range, greatly reduced the times of battery discharging, can    extend the battery service life.

●Has the perfect cold-start, in no electricity power state, batteries can be used directly to start UPS to provide   stable AC power for the user load to meet users’ emergency needs.

●Output precise synchronization phase with the network, to protect the safety and reliability of static electronic   bypass.

●Through RS232 communication interface computer can realize UPS monitoring and management function,     including AC power status and monitoring, recording, analyzing UPS working status, schedule power on/off UPS, monitoring UPS itself testing management, power interruption alarm, automatic power off system safely in very low battery status, send messages to users by mobile phone or email.

● Equipping SNMP adapter through RS232 communication interface through, constituting network remote management system to realize remote centralized monitoring and management, management software supports operating systems: Novell, Netwer, MS-windows95, MS-windows98, MS-windows2000, MS-windowsNT, MS- windowsXP, FreeBSD, Unix, Linux, etc.

●UPS with LED and LCD dual display system, when UPS works abnormally caused by the abnormal city power or city power failure ,UPS internal microcomputer CPU will display system fault state through the LED and LCD Dual display system, so that the user or technical managers can learn abnormal causes accurately in order to make the right deal timely.

●Ultra wide AC power input voltage and frequency range, can be compatible with any form AC power, including the adaptation of industrial power generation, wind power, etc.

LED and LCD dual displaying system, can clearly and accurately displaying UPS operating status, so man-machine communication zero distance, truly realize friendly man-machine interface.

Internal partition modular design with compact size, beautiful and elegant appearance, small footprint.

●Using advanced anti-electromagnetic interference technology, fully in line with international standards, has good electromagnetic compatibility, and maximizing eliminates load equipment electronic interference.

●Input and output electronic circuit with a harmonic filter, the maximum elimination harmonic interference caused by UPS to the network environment.
