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.


Products & Services Related to Power Supplies
AC-DC Adapters
AC-DC adapters accept AC input voltage directly from a wall outlet, and output DC voltage.
Current Sources
Current sources provide reliable current for electrical component testing and for powering specialized components.
DC Power Systems
DC power systems provide continuous DC power through multiple outputs.  Most DC power systems include a battery backup, temperature compensation, and other features.
High Voltage Power Supplies
High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts.
Medical Power Supplies
Medical power supplies produce conditioned outputs for medical devices, instruments, and equipment.
Power Rectifiers
Power rectifiers are electrical devices that convert alternating current (AC) to direct current (DC). They are an integral part of telecom rectifiers for the telecommunications industry, and in battery chargers, DC power systems, and other power system devices.
Programmable Power Supplies
Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency. They include a processor, voltage/current programming circuits, current shunt, and voltage/current read-back circuits.
