  • Page 38: Wire Termination

    2. Wire size should be selected to enable voltage drop per lead to be less than 1.0V at the rated Output current. Although units will compensate for up to 5V in each load wire, it is recommended to minimize the voltage drop (1V typical maximum) to prevent excessive output power consumption from the power supply and poor dynamic response to load changes.

  • Page 39: Inductive Loads

    Twisting the load wires reduces the parasitic inductance of the cable, which could produce high frequency voltage spikes at the load and the output of the power supply, because of current variation in the load itself. The impedance introduced between the power supply output and the load could make the ripple and noise at the load worse than the noise at the power supply rear panel output.
  • Page 40 150V to 600V Models WARNING Hazardous voltages may exist at the outputs and the load connections when using a power supply with a rated Output voltage greater than 40V. To protect personnel against accidental contact with hazardous voltages, ensure that the load and its connections have no accessible live parts.
