Voltage Regulators Specifications

Help with Voltage Regulators specifications:

General Specifications

	Phase:
	Your choices are...
	Single Phase		Single-phase power is used with computers, office equipment, and many types of laboratory instruments. Most standard commercial voltages are single-phase.
	Three Phase		Three-phase power is used mainly with industrial motors and industrial machinery.
	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.
	Frequency:
	Your choices are...
	50 Hz		50-Hz is used in Europe.
	60 Hz		60-Hz power is used in the United States, Canada, Japan, and many other countries.
	400 Hz		400-Hz power is used in aerospace applications.
	Other		Other unlisted frequencies.
	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.
	Configuration / Form Factor
	Your choices are...
	Computer Board		Devices install into the slot of a computer backplane, or use a board configuration that requires enclosure within a case.
	Portable / Benchtop		Portable or benchtop units are designed to be moved or carried. They often include a case with a handle or handles.
	Hard Wired		Hard-wired devices are mounted permanently in, on, or near the supplied device. Usually, the input and output connections are also permanent.
	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.
	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.
	Wall Mount		Devices are wall-mounted.
	Floor / Free Standing		Devices do not need to be mounted, but can instead stand on their own. Typically, floor-standing or free-standing voltage regulators include large or high-power class conditioners.
	Other		Other unlisted or specialized mounting configurations.
	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.

Performance

	Power Rating		Power rating is usually expressed in volt-amps, the product of the maximum-allowable RMS voltage and the maximum-allowable RMS 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.
	Input Voltage		Input voltage is the nominal line voltage to which the device is connected.
	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 Voltage		The output is a regulated or conditioned 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.
	Voltage Regulation		Voltage regulation measures a device's ability to maintain a constant voltage across changes to the input voltage. It is measured as a percentage of the nominal 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.
	Load Regulation		Load regulation is the ability to maintain a constant output voltage with changes in load. It is measured as a percentage of the nominal 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.
	Efficiency		Voltage regulator efficiency is expressed as a percentage of the ratio of the output voltage to the input 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.
	Number of Outlets (if Applicable)		Although many voltage regulators supply a single outlet for conditioned power, some feature multiple outlets. This is sometimes the case with equipment that does not consume a great deal of power, such as computers or light instrumentation.  The number of outlets is not applicable for hard-wired devices or specialty conditioners, such as boards.
	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.
	Operating Temperature		This is the full-required range of ambient operating temperature.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

Features

	Your choices are...
	Readout or Indicators?		Readouts or indicators are visual displays that provide information about status or performance. They may include simple LED indicators or more elaborate readouts.
	Adjustable Output Voltage		The output voltage of the regulator can be adjusted.
	Bypass Switch?		A bypass switch is designed to take a device off-line without requiring its physical removal, thus permitting the passage of unconditioned power.
	Instrumentation		The voltage regulator has embedded electrical instruments such as ammeters, voltmeters, power meters, etc.
	NEMA Enclosure		The regulator is packaged in a NEMA enclosure. NEMA is the National Electrical Manufacturers Association.
	Isolation Transformer		The voltage regulator has an input transformer for isolating the device.
	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.
