5  System description 

The UPS is built following the principle of double conversion. The UPS 

supplies an uninterrupted, single-phase voltage to users with mission-critical 

applications. In addition to supplying consumer loads, the equipment also 

keeps its internal batteries in a fully charged state. In the event of a power 

failure or power fault (e.g. voltage fluctuation), the UPS continues, without 

interruption, to deliver a clean voltage supply to the UPS output. In support 

mode, the energy is drawn from the battery pack.

The block circuit diagram shows the individual modules of the equipment and 

provides a general impression of how they interact.  

If the mains power failure exceeds the autonomy time of the UPS, it shuts 

down to prevent deep discharging of the batteries. When the mains power 

supply is restored, the UPS restarts automatically, supplies the consumer 

loads and controls the charging of the battery pack. 

Outstanding performance characteristics oft he MHD Online UPS are: 

o

 

No interruptions or signal changes in case of primary mains failure. 

o

 

Perfect sinus voltage on the output oft he UPS. The quality of the 

output voltage is much better than the mains voltage of the in-house 

network. 

o

 

Processor controlled bypassing mode (bypass); 

o

 

Power Factor correction on the input (>0,95); 

o

 

High efficiency degree of the inverter >90% DC / AC; 

o

 

High-performance communications interface (RS232 interface); 

o

 

LCD displays status and operation mode
