Description
EXT R/V CONT
1 Used for voltage/resistance control of CC, CR, CV
and CP mode. 
 
0V to 10V corresponds to 0% to 100% of the rated 
current (CC mode), rated voltage (CV mode), or 
rated power (CP mode). 0V to 10V corresponds to 
the maximum resistance to minimum resistance 
(CR mode) 
 
0Ω to 10kΩ corresponds to 0% to 100% or 100% 
to 0% of the rated current (CC mode), rated 
voltage (CV mode), or rated power (CP mode). 0Ω 
to 10kΩ corresponds to maximum resistance to 
minimum resistance or minimum resistance to 
maximum resistance (CR mode)
