General Information 19
Output Characteristic
General
The power supply can operate in either CV (constant voltage) or CC (constant current) over its voltage and current ratings
(see Table 1-l). The operating locus is shown by the Output Characteristic Curve in Table 1-2. The operating point is
determined by the voltage setting (V
s
), the current setting (I
s
), and the load impedance. Two operating points are shown.
Point 1 is defined by the load line cutting the operating locus in the constant-voltage region. This region defines the CV
mode. Point 2 is defined by the load line cutting the operating locus in the constant-current region. This region defines the
CC mode.
Downprogramming
The power supply can sink current for more rapid down programming in the CV mode. For Series 664xA and 665xA
supplies, this capability is defined by the second quadrant area (-I
s
) of the Output Characteristic Curve. These supplies can
sink about 20% of their maximum rated positive output current. For Series 667xA and 668xA power supplies, this is an
uncharacterized current-sinking area that provides a limited downprogramming capability.
Specifications and Supplemental Characteristics
Tables 1-1 through 1-4 list the specifications and supplemental characteristics for the Series 664xA, 665xA, 667xA, and
668xA power supplies. The organization is as follows:
