    minimize the voltage drop (1V typical maximum) to prevent excessive output power consumption from the power supply and poor dynamic response to load changes. Please refer to Tables 3-2 and 3-3 for minimum wire length (to limit voltage drop) in American and European dimensions re- spectively.

  • Page 27: Noise And Impedance Effects

    Where shielding is used, connect the shield to the chassis via a rear panel Ground screw. Even if noise is not a concern, the load and remote sense wires should be twisted-pairs to reduce coupling, which might impact the stability of power supply. The sense leads should be separated from the power leads. Twisting the load wires reduces the parasitic inductance of the cable, which could produce high fre- quency voltage spikes at the load and the output of the power supply, because of current variation in the load itself.
