Basic Operation
This chapter describes basic features and operations of the
PMC-A such as remote sensing, master-slave parallel opera-
tion, series operation.
4.1 Constant Voltage (CV) and Constant
Current (CC) Power Supplies
The product has functions for constant voltage power supply to
maintain a fixed/regularized output voltage, and for constant
current power supply that maintain a fixed output current, even
as the load changes. The state of operation for constant voltage
supply is called “CV mode”, and for constant current supply,
“CC mode”. These operating modes are determined by the fol-
lowing three values.
• Output voltage setup value (V
S
)
• Output current setup value (I
S
)
• Load resistance value (R
L
)
These operations are detailed in the following.
