Style / Mounting



	Your choices are...
	Board Mount		Through hole technology (THT) mounts components on a printed circuit board (PCB) by inserting component leads through holes in the board and then soldering the leads in place on the opposite side of the board. Surface mount technology (SMT) adds components to a printed circuit board (PCB) by soldering component leads or terminals to the top surface of the board. SMT components have a flat surface that is soldered to a flat pad on the face of the PCB. Typically, the PCB pad is coated with a paste-like formulation of solder and flux. With careful placement, SMT components on solder paste remain in position until elevated temperatures, usually from an infrared oven, melt the paste and solder the component leads to the PCB pads.
	Circuit Board		Devices are circuit boards.
	Open Frame		Open-frame power supplies have exposed circuitry and components. They are simply circuit boards to which all of the circuitry and components attach on one side.
	Enclosed		Enclosed power supplies house all of the circuitry and components inside a case. The input and output connections are enclosed.
	Module		Devices are modular.
	DIN Rail		Devices mount on a standard DIN rail. DIN is an acronym for Deutsches Institut für Normung (DIN), a German national organization for standardization.
	Desktop		Devices sit on a desktop or shelf.
	Rack Mount		Devices mount in racks and come with hardware such as rail guides, flanges, or tabs. Some rack-mounted devices fit in a standard 19” telecommunications rack.
	Wall Mount		Devices are wall-mounted.
	Cabinet		Devices include a floor-standing cabinet.
	External Power Supply		The power supply is located outside the device being served.
	Other		Other unlisted, specialized, or proprietary styles.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

General Specifications


	Output Power		The output power of the device, measured in watts.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Efficiency		Efficiency is the output power divided by the input power, measured as a percentage. For an AC output, the efficiency is defined as the output power divided by the apparent input power
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Number of Outputs		The number of output ports.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Voltage Accuracy		The output voltage accuracy is a percentage of the rated voltage.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

AC Output


	Phase
	Your choices are...
	Single-Phase		The AC output is single-phase; the more commonly used AC type. Single-phase is often, but not exclusively used for lower voltage applications.
	Three-Phase		The AC output is three-phase. Three-phase inputs are typically used for high voltage power supplies.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Waveform
	Your choices are...
	Sine Wave		Devices can produce sine wave outputs.
	Square Wave		Devices can produce square wave outputs.
	Triangular Wave		Devices can produce triangular wave outputs.
	Other		Other unlisted waveform outputs.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	AC Output Voltage		Enter the AC output voltage.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Output Frequency		The output frequency.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	AC Output Current		The output AC current.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Apparent Power (VA Rating)		Apparent power is the product of the root mean square (RMS) current and the RMS voltage of the AC output. This amount is the same as the VA rating.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Features / Compliances


	Standards / Compliances
	Your choices are...
	REACH		Registration, Evaluation and Authorization of Chemicals (REACH) is a European Union standard for supply chain information exchange. The REACH standard provides a supplier portal to facilitate communication with suppliers. If a product is submitted via the trader portal, the supplier portal sends an e-mail to the relevant exporter requesting that they register and give details of the substances contained in the product. If more complex products are involved, exporters can also include their own sub-suppliers in the automatic substance query.
	RoHS Compliant		Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl, and polybrominated diphenyl ether.
	WEEE Compliant		Waste Electrical and Electronics Equipment Regulations (WEEE Regulations) is a European Union Directive that is designed to encourage the reuse, recycling, and recovery of electrical and electronic equipment, and to improve the environmental impact and performance of this equipment. WEEE also establishes the requirement and criteria for the collection, treatment, recycling and recovery of this equipment. It makes producers responsible for financing these activities, and retailers and distributors must provide a means for consumers to return used or obsolete equipment without charge.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Features
	Your choices are...
	Computer Interface		Devices provide a computer interface that can be used for remote monitoring or control.
	Over Current Protection		Over current protection is internal circuitry that limits or shuts down the current output during over current conditions.
	Over Voltage Protection		Over voltage protection is internal circuitry that limits or shuts down the voltage output during over voltage conditions. Typically, over voltage protection is provided for the primary output.
	Power Factor Correction		Power factor correction is used to correct the phase difference between voltage and current in order to optimize power output.
	Pure Sine Output		Pure sine output produces a very high quality, pure sine waveform output.
	Remote On / Off Switch		Devices can be turned on and off remotely.
	Short Circuit Protection		Short circuit protection may include electronic current limiting and thermal resets with automatic recovery.
