Page 187: External Voltage Control - Overview
EXTERNAL CONTROL External Voltage Control - Overview Background External voltage control of the CC, CR, CV, CP and Cx+CP mode is accomplished using the J1 connector on the rear panel. An input voltage of 0- 10V corresponds to 0% - 100% of the rated current (CC mode), rated voltage (CV mode), or rated power (CP mode).
Page 188: External Voltage Control - Operation
PEL-3000A/AH series User Manual The input impedance for external voltage control is Note 10kΩ. Use a stable voltage supply for the external voltage control. When using external voltage control, make sure no Caution more than ±11V is applied across pins 1 and 3. Exceeding this voltage could damage the PEL- 3000A/AH.
Page 189 EXTERNAL CONTROL Under EXTernal Control, the panel or remote Note command will no more control the unit. The front panel will show the icon “EXT”.
