Isolation

Absence of DC current pass between two circuits. In a PSU isolation is provided by transformers. Commercially available AC-DC PSU are normally isolating. Low input voltage DC-DC PSU, such as car phone chargers, are often non-isolating. Note that isolation does not necessarily mean a complete absence of current path- some low-level AC currents can still flow from input to output through physical and/or stray capacitances.
