Система бесперебойного питания

KD-SeriesUninterrupted Power System is well-designed for the safe protection of computer networks and sophisticated electronic equipment, electrical equipment at complex network environment. Adopting on line 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. advantages, to meet the needs of the load equipment protection in complex grid environment interference caused by UPS to the network environment.
