APC VT40000VA-400V Rack‑Mounted Power Backup System

The chemical composition or classification of a battery, such as alkaline, lithium‑ion, NiMH, or lead‑acid. It indicates the energy storage technology used in the product and helps users identify compatibility with devices that require specific battery chemistries.

A list of official certifications or compliance marks that the product has received from regulatory bodies, safety organizations, or industry standards groups. Each entry represents a distinct certification such as CE, FCC, RoHS, UL, or WEEE, and may include additional details like version numbers or specific test reports.

The type of electrical connector or inlet that a device uses to receive power, such as IEC C14, NEMA L6-20P, Schuko, or custom industrial plugs. It indicates the physical shape and pin configuration required for proper connection and compatibility with mains supplies.

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.

List of physical or logical interfaces that allow communication between a hard drive and other devices, such as SATA, M.2 PCIe, U.2, SAS, NVMe, or other standard connections.

The sound intensity produced by a product, expressed in decibels (dB) or sones. It indicates how loud the device is during operation and helps users assess suitability for quiet environments.

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 altitude interval (in meters) at which a product or component ceases to function correctly due to environmental factors such as reduced atmospheric pressure, temperature changes, or other elevation‑related effects. The value is expressed as a minimum–maximum range and applies to any device that has documented limits for operation above or below certain heights.

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 types and quantities of electrical outlets or connectors that a device provides for external equipment, such as power sockets (e.g., C13, C19, BS 1363) or other interface plugs. The value is expressed as a textual list indicating each connector type and the number of available ports.

The electrical power that a device can deliver or consume, expressed in watts (W). It represents the actual power output under normal operating conditions and is useful for comparing performance across similar devices.

The maximum electrical power that a device can deliver or consume, expressed in volt‑amps (VA). It represents the apparent power rating of the product and is used to compare capacity across similar equipment.

The mass of the product expressed in a standard unit such as grams or kilograms. It represents how heavy the item is and can be used for shipping calculations, handling instructions, or consumer information.
