Most power supplies on the market today provide good input and output isolation. However,
power supplies which do not provide isolation (or have high leakage capacitance), coupled
with accidental AC power line interchanges, present serious ground fault problems for
installers. With a ground fault, the signal reference between subsystems may be 115 VAC
apart. If these subsystems are interconnected, the large potential difference can cause
equipment damage or personal injury. L-1 Identity Solutions recommends using a dedicated
regulated DC power supply.

All factory-supplied power supply assemblies are either switching or regulated linear supplies
and are isolated for safety and to minimize ground loop problems.
