Hewlett Packard Enterprise P9Q37A power distribution unit (PDU) 1U

The frequency of the alternating current supplied to a power supply or charger, expressed in hertz (Hz). It indicates the acceptable operating range for the electrical mains that powers the device, ensuring proper functionality and safety.

A list of the different AC power outlet or coupler types that a product supports, such as C13, C19, C20, Type F, Type G (BS 1363), NEMA 5‑15R, etc. Each entry represents a distinct electrical connector that can be used to supply power to the device.

The total count of standard AC power sockets available on the device, such as a power distribution unit or surge protector. This value indicates how many separate appliances can be connected simultaneously.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

The highest electrical current that a device can safely draw from its power source, expressed in amperes (A). It indicates the maximum load the product is designed to handle during normal operation and helps users verify compatibility with power supplies or sockets.

The physical configuration or method used to secure a product, such as clamp, bolt‑through, vertical, horizontal, rack mounting, freestanding, wall mounting, or other installation approaches.

The electrical voltage that a product accepts from its power source, expressed in volts (V). It indicates the minimum and maximum supply voltages compatible with the device, covering both AC and DC inputs where applicable.

The range of altitudes (in meters) at which a product or component can operate reliably without performance degradation due to changes in atmospheric pressure, temperature, or other altitude‑related effects.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

A list of the types of power distribution units (PDUs) that a product can support or be part of, such as Metered, Basic, Switched, Managed, Monitored, and combinations thereof. Each entry represents a distinct PDU configuration that may provide features like metering, switching, monitoring, or management.

The type of electrical power connector or plug used by the product, such as IEC, NEMA, BS1363, C14, C20, etc. It indicates which standard socket or coupler is required for connecting the device to a mains supply or other equipment.

The height of a device measured in rack units (U), where one U equals 1.75 inches (44.45 mm). The value is expressed as an integer such as "2U" or a numeric measurement with the unit, for example "3.5U" or "61.25 mm". This attribute indicates how many rack units a product occupies when installed in a standard server rack.

The general category or style of the product, such as laptop, printer cartridge, or cooling fan. It helps buyers quickly identify the nature of the item and compare similar products.
