Page 191 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 192: 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.
