| 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. | ||

|
| ||
| 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. | ||
