Standby Power Rules Reach AV Hardware Ahead Of 2027

Commission Regulation (EU) 2023/826 has been mandatory since 9 May 2025, replacing the older standby rules, and it is quietly reshaping the specification sheets of AV hardware sold into Europe. The limits are simple to state. Off mode must not exceed 0.50W. Standby without a display is capped at 0.50W, standby with a display at 0.80W, and networked standby at 2.00W for ordinary devices, rising to 8.00W only for equipment with high network availability. Devices must enter a low-power mode automatically, and the declared consumption in each mode has to match measurement within about ten per cent. From 9 May 2027 the off-mode ceiling drops to 0.30W.

For consumer white goods that is old news. For networked AV it is not, because of multiplication. A single decoder drawing 2W in networked standby sounds like a rounding error. Five hundred of them, which is a mid-size campus or a transport hub, is a kilowatt running continuously, twenty-four hours a day, whether or not anyone is in the building. Add AV-over-IP endpoints, PoE-powered touch panels, ceiling microphones, network amplifiers and the matrix at the head end, and the idle load becomes a line item in the building's energy model and, increasingly, in its tender documents. Procurement teams that already ask for power figures per mode are now asking for the whole project's idle load, and they are asking before the design is frozen rather than after commissioning.

The 0.30W step is where engineering gets interesting. Getting below 0.50W usually means a switched-mode supply with a well-behaved no-load characteristic and a microcontroller that sleeps properly. Getting to 0.30W with a networked interface alive, a front-panel LED and a relay on the mains input is a different problem, because the wake path itself consumes power. Designers end up choosing between a true mains disconnection with a low-leakage standby rail, a relay plus a capacitive supply, and a network processor that can be put into a deep sleep with wake-on-LAN handled by the PHY. Each choice has consequences for how fast the box comes back, whether it can be woken remotely at all, and how it behaves after a power cut, which is exactly the scenario a venue actually cares about.

For buyers, the practical checklist is short and worth using. Ask for a table of measured consumption in off, standby, display standby and networked standby, with the test standard cited, rather than a single headline wattage. Ask what triggers the automatic low-power transition and how long it takes, because a device that only sleeps when someone presses a button does not comply in spirit. Ask what the unit draws when the network link is up but no stream is running, since that is the state most installations live in. And ask whether the manufacturer can supply the technical file and registration support that a European distributor will need.
