Protection 

The  ADG-P  series  has  complete  protection  functions  divided  into  two  classes:  the 

first  type  protection  includes  overvoltage  and  overcurrent;  while  the  second  type 

protection includes overtemperature and over/under input voltage. In the first class, 

the protection trigger point is set by the users, while the second class protection is 

auto detected by the system hardware protection circuit. 

 

3.8.1

 

Overvoltage Protection (OVP) 

The  Overvoltage  Protection  (OVP)  function  allows  the  product  to  shut  down  the 

output, if it were to exceed the set value of OVP. When OVP occurs, the condition 

OV

 

displays under the 

Voltage

 item and the buzzer alarms. To clear the display, press the 

Reset

 icon. 

Make sure to adjust the set value of output voltage or  OVP point before restarting 

the output. The set value of OVP is within the range of 5-115% of the rated value.
