Signage power sits in the IT and AV regulatory frame, with a commercial-installation twist:<\/p>\n
\n- Safety:<\/strong> IEC\/EN 62368-1 is the current hazard-based standard for IT and AV equipment; some constructions are assessed to the IEC 61558 series instead.<\/li>\n
- EMC:<\/strong> FCC Part 15 in the US \u2014 Class A for commercial environments<\/strong>, Class B for residential. Most signage is Class A, but confirming this early avoids a registration surprise.<\/li>\n
- Efficiency:<\/strong> DOE Level VI \/ EU CoC Tier 2 for external supplies; continuous duty makes this an operating cost, not a formality.<\/li>\n
- Regional marks:<\/strong> CE\/CB for Europe, UL\/cUL or ETL for North America, plus country schemes such as INMETRO in Brazil, BIS in India and others.<\/li>\n<\/ul>\n
We certify per model and per market rather than claiming one certificate covers everything; certification by country<\/a> explains which schemes transfer cleanly and which need local registration.<\/p>\nDigital signage power specification table<\/h2>\n

\nFrequently asked questions<\/h2>\nWhat voltage do digital signage displays use?<\/h3>\nMedia players and small panels usually run 12V or 19V; LED tiles and larger low-voltage panels use 24V or 48V.<\/strong> Large commercial displays generally take AC mains directly and contain their own supply, so confirm which part of the system you are actually powering before requesting a quote.<\/p>\nDo large commercial displays use an external adapter?<\/h3>\nUsually no \u2014 most 43\u2033 and larger commercial displays have an internal supply and an IEC mains inlet.<\/strong> The external supply in a signage installation typically powers the media player, a small display, or an LED tile.<\/p>\nHow do I size power for a 7\u00d724 signage deployment?<\/h3>\nSize for continuous duty at the real enclosure temperature, with a stated derating curve and 20\u201330% headroom \u2014 not for the peak wattage on a benchtop.<\/strong> Then confirm light-load efficiency, because the supply idles for much of the night.<\/p>\nDoes brightness change the power requirement?<\/h3>\nYes, roughly in proportion, and outdoor panels can draw several times an indoor screen of the same size.<\/strong> Content matters too: a bright, high-motion loop pulls more than a dark static menu, so size for the worst realistic content.<\/p>\nHow do I handle heat in a sealed signage enclosure?<\/h3>\nSpecify higher efficiency and higher-temperature capacitors, derate more, and keep the supply away from the panel’s hot surface.<\/strong> Cooler operation is the difference between a five-year life and a two-year life.<\/p>\nWhat about outdoor digital signage power?<\/h3>\nRate for the hottest hour, use IP65 or better with potting where the supply is exposed, and specify UV-resistant cable jackets.<\/strong> Outdoor cabinets carry solar gain on top of their own waste heat, so the thermal margin must be larger than indoor designs.<\/p>\nWhich certifications does a signage power supply need?<\/h3>\nIEC\/EN 62368-1 for safety, FCC Part 15 Class A for commercial environments, CE\/CB for Europe, plus DOE Level VI or CoC Tier 2 efficiency<\/strong> and country marks for the destination market. A digital signage power supply OEM should certify per model and market rather than claim one certificate covers all.<\/p>\nWhat MOQ and lead time apply for custom signage power supplies?<\/h3>\nFrom 200 pcs per model at Paiyi Power, with samples in about a week and first production 5\u20136 weeks after sample approval.<\/strong> Modified-standard builds usually need no new tooling. Evaluate first samples with our sample evaluation checklist<\/a>.<\/p>\nWhy do signage power supplies fail in summer?<\/h3>\nHeat.<\/strong> Enclosures run well above ambient in summer, capacitor life roughly halves for every 10 \u00b0C rise, and a supply specified at 25 \u00b0C is often a much smaller supply at 55 \u00b0C. Specify 105 \u00b0C capacitors, a real derating curve, and enough margin for the hottest day rather than the average one.<\/p>\n
