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 (Vs), the current setting (Is), 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 (-Is) of the Output Characteristic Curve. These supplies can sink about 20% of their maximum rated positive output current. For Series 667xA, 668xA, and 669xA power supplies, this is an uncharacterized current-sinking area that provides a limited downprogramming capability.
