Page 220: Operating Mode Description
PEL-3000 User Manual Operating Mode Description CC Mode When the unit is set to CC mode it will operate CC Mode as a constant current load when connected to a constant voltage source. This means the unit will sink a designated amount of current, up to the rated power level, regardless of the voltage.
Page 221: Cr Mode
APPENDIX CC + CV Mode Load Input Voltage CV level Load Current CC Current Value Note that when the source voltage is less than the CV level, no current will flow due to a very high impedance. CR Mode When the unit is set to CR mode it will operate CR Mode as a constant resistance load when connected to a constant voltage source.
Page 222: Cp Mode
PEL-3000 User Manual When CR+CV mode is enabled, the unit will act CR+CV Mode as constant resistive load after the input voltage is greater than the user-defined CV level. At the CV level, the unit works as a constant voltage load.
Page 223 APPENDIX CP Mode Load Input Voltage CP Value Load Current When CP+CV mode is enabled, the unit will act CP+CV Mode as a constant power load after the input voltage is greater than the user-defined CV level. At the CV level, the unit works as a constant voltage load.
Page 224: Cv Mode
PEL-3000 User Manual CV Mode When the unit is set to CV mode it will operate CV Mode as a constant voltage load when connected to a constant current source. This means the unit will maintain a set voltage level, up to the rated power, regardless of the input current.
