Safety Considerations This power supply is a Safety Class 1 instrument, which means it has a protective earth terminal. That terminal must be connected to earth ground through a power source equipped with a 3-wire ground receptacle. Refer to the Safety Summary page at the beginning of this guide for general safety information. Before installation or operation, check the power supply and review this guide for safety warnings and instructions. Safety warnings for specific procedures are loc

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 ), the current setting (I ), and the load impedance. Two operating points are shown. s s Point 1 is defined by the load line cutting the operating locus in the constant-voltage regio
