KGK Series UPS
Transformer based Online Double Conversion
Uninterruptible Power Supply

High Protection
Online Double Conversation UPS systems are ideal for the protection of the mission critical processes with its transformer based architecture. The inverter topology uses 3 full-bridge 6 IGBT modules with switching at 20kHz frequency; so for the non-linear and reactive loads the output waveform has no distortion. For the output, two mechanical contactors are used with thyristor switch with no break transfer time so the load is always secure..

Extended Battery Life
GESS transformer based, line interactive online UPS systems provide longer operational efficiency as transformer-less UPS systems bring operational risks and downtime due to malfunction especially for industrial uses where voltage transients, created by a degraded mains supply, can seriously damage both UPS and the load. For 3/ 3 systems, each phase is controlled independently and this capability provides three phase systems smoother operation.

Environmentally Friendly
GESS online UPS systems have a modular architecture, meaning that they' re built with a number of electronic cards to control each unit instead of a large, single motherboard; thus it would be enough to replace the that particular PCB to fix the device in case of a failure. It can be translated into significantly lower spare part cost and shorter maintenance time
