OVP setup 
Background  
Over Voltage Protection (OVP) protects SPS and 
DUT from excessive output Voltage. The user sets 
the maximum output voltage limit before 
operation. When the output voltage exceeds this 
limit, the output is shut off immediately. 
 
1.  With the machine off, turn 
the voltage output to 
maximum.

clockwise) 
 
3.  Turn on the SPS. 
 
 
4.  Adjust the voltage output 
to slightly above the 
desired OVP level.

5.  Turn the OVP adjuster 
until the voltage displa
