mode and the reporting of the results for edge equipment.
The measurement of power and energy use in non-active mode, other than networked standby
mode, is covered by IEC 62301, including the input voltage range.
This document applies to edge equipment that are powered by:
– low voltage mains AC power (𝐿𝐿𝐿𝐿≤ 1000 𝐿𝐿 𝐴𝐴𝐴𝐴), or
– an external power supply that provides low voltage (𝐿𝐿𝐿𝐿≤ 1000 𝐿𝐿) or extra low voltage (𝐸𝐸𝐿𝐿𝐿𝐿≤
50 𝐿𝐿) AC or DC power, or
– a separate source of extra low voltage DC power (𝐸𝐸𝐿𝐿𝐿𝐿≤ 50 𝐿𝐿 𝐷𝐷𝐴𝐴), or
– an internal main battery.
Conditions that are out of scope:
– active mode (primary function),
– other non-active mode (which are either covered by IEC 62301 or by specific product group
standards),
– conditions where main batteries are being charged other than maintenance mode,
– disconnected condition of the equipment.
This document applies to the following product groups where a networked standby mode is
present:
– edge equipment with a network reactivation function, such as household appliances,
information technology equipment, audio, video and multimedia systems and equipment,
– digital radio receivers with an emergency warning function,
