Description

The  KVM  Series  is  a  single  phase  undervoltage  monitor  designed  to  protect  sensitive  equipment  against 
brownout undervoltage conditions.  The compact design and encapsulated construction make the KVM an 
excellent choice for OEM equipment. 

Operation

The  output  relay  is  energized  and  the  LED  glows 
green  when  the  input  voltage  is  above  the  reset 
voltage threshold. If the input voltage drops below the 
undervoltage  set  point,  the  output  relay  and  LED  will 
de-energize. The output relay will remain de-energized 
as long as the input voltage is below the reset voltage.  
Reset is automatic when the input voltage returns to a 

normal range.

See accessory pages for 

specifications.
