ON-LINE UPS
On-Lıne UPS

 

In this type of UPS systems, loads are fed from inverters. When the network is active, batteries are being charged and also loads are fed via invertor which has same frequency with main network. When then network voltage is interruptedor out of tolerances, battery mode starts. Battery and inverter couple supply stabilized power until the stored energy finishes or AC grid gets in the tolerances. These are the systems which provide high protection against powers chosen for critical loads. In case of over load or fault in power source, the output is delivered to static by-pass line with static transferring switches. Manual by-pass is used for service staff to make comfortable maintenance by cutting whole power from the system.
