|Power supplies are devices that produce AC or DC power.
This grouping includes current sources, DC power supplies, AC-DC adapters,
DC-DC converters, AC power sources, and DC-AC inverters. Current sources
provide reliable current for electrical component testing and for
powering specialized components. DC power supplies accept AC input
and provide one or more DC outputs for a wide variety of computer
and industrial applications. AC / DC adapters accept AC input voltage
directly from a wall outlet, and output DC voltage. DC-DC converters
accept DC input and provide regulated DC outputs for computers, telecommunications,
and process control applications. AC power sources provide alternating
power and will typically have adjustable output values for the testing
of component response at various voltage, current and frequency levels.
DC to AC power inverters are used for converting direct current (DC)
into alternating current (AC). They are also known as DC to AC converters.
Rectifiers accept AC input and provide one or more DC outputs for
a wide variety of computer and industrial applications. Style, output,
display, application, and features are all important to consider when
specifying power supplies.
