Uninterruptable Power Supply UPS 

The complete ETV 1591-H panel consists of the actual ETV 1591-H function block and the 
preceding UPS current supply (battery and electronics), 
 
 

5.1 

Simplified Block Diagram 

The  battery  is charged  with  the  connected  +24  V  main supply.  The  UPS is  active  when a 
failure of the ex24 V main supply is detected. The UPS then provides the required 
voltage  to  the  ETV  1591  functional  block  from  the  rechargeable  battery  to  enable  a  safe 
shut down of the operating system.  
 
Basic function of the UPS:
