chapter, page 9. 
Setting OVP/OCP/UVL Levels 
 
The OVP level and OCP level has a selectable 
range that is based on the output voltage and 
output current, respectively. The OVP and OCP 
level is set to the highest level by default. The 
actual selectable OVP and OCP range depends on 
the PSU model.  
When one of the protection measures are on, ALM 
indicator is lit red on the front panel and the type 
of alarm is also shown on the display. The 
ALM_CLR button can be used to clear any 
protection functions that have been tripped. By 
default, the output will turn off when the OVP or 
OCP protection levels are tripped. 
The UVL will prevent you from setting a voltage 
that is less than the UVL setting. The UVL setting 
range is from 0% ~ 105% of the rated output 
voltage.
