AC AC Wall Adapters
AC-AC Wall Adapters are a completely enclosed unit that converts an alternating current voltage input to a lower alternating current voltage output. The AC wall adapters come with or without a cord. The corded adapters come with a barrel plug, phono plug, rectangular connector, or stripped & tinned wire leads.
AC DC Configurable Power Supply Chassis
Configurable power supply chassis products are the outermost component of a user-configurable power supply system. Such systems are modular in nature, allowing rapid construction of semi-custom power conversion products by the insertion of output-specific conversion modules into an outer chassis that provides mechanical containment and typically a number of electrical factors that are common/shared among the conversion modules, such as rectification and power factor correction. Product series represented in this family are user-configurable and do not require specialized tools or training for assembly.
AC DC Configurable Power Supply Modules
AC-DC Configurable Power Supply Modules are the circuit board portion of a configurable device that converts an alternating current input into a direct current output with voltages ranging from 2.5 V to 48 V, current from 2.5 A to 53 A, and a power maximum of 33 W to 600 W.
AC DC Converters
AC-DC Converters convert an alternating current input voltage (10 V to 766 VAC) to a direct current output voltage (-54.5 V to 400 VDC). The AC-DC converter can be board mounted on- or off-board. Off-board power sources are available with 1 to 10 outputs, while on-board are available with 1 to 3 outputs. The output current ranges from 10 mA to 1000 A with wattage ratings of 1 W to 10,080 W.
AC DC Desktop, Wall Adapters
AC to DC desktop and wall adapters are completely enclosed devices that convert an alternating current (AC) voltage in to a different direct current (DC) voltage output.
DC DC Converters
DC-DC Converters convert a direct current voltage input into a different direct current voltage output. They have essentially the same wattage rating on both the input and the output, minus switching losses. DC-to-DC converters can be mounted on- or off-board. They come in a variety of inputs, outputs, and packages, and can have single or multiple output options.
LED drivers provide a constant current, constant voltage, or a combination of both to provide a steady flow of power to residential or commercial LED lighting elements. Topologies include AC to AC, AC to DC, boost, buck, and buck-boost. Because they can accept a wide range of input voltage, LED drivers are selected by choosing the minimum and maximum input voltage, the output voltage and current (max), the overall power output, and dimming features.
Power over Ethernet (PoE)
Power over Ethernet (PoE) power supplies allow designers to transmit electrical current and data over a single Ethernet connection. Remote devices are powered through Ethernet cabling, eliminating the need for batteries, local power adaptors, and additional power cabling.
