Product Overview
The 24V 3A Power Supply 72W AC/DC Adapter delivers regulated 24V DC at up to 3A, designed for applications that require continuous, reliable power in a compact form factor. The universal AC input (100–240Vac, 47–63Hz) ensures compatibility with power grids worldwide, while the standard 5.5×2.1mm DC barrel connector mates directly with most 24V equipment. Measuring just 90×46×32, the 24V 3A Model fits neatly into tight enclosures and equipment racks without obstructing adjacent outlets.

Design & Build Quality
The 24V 3A Model employs a high-frequency switching topology with premium 105°C-rated capacitors, achieving 88% energy efficiency (DoE Level VI) and keeping surface temperature below 50°C under continuous full load. This thermal headroom makes the model suitable for enclosed cabinets, equipment racks, and installations where airflow is limited. The fanless design ensures completely silent operation — no mechanical noise in studios, offices, or bedrooms.
Typical Applications
With 72W of continuous output capacity, the 24V 3A Model serves a broad range of 24V DC loads:
• LED Strip Lighting — Drives SMD 5050, 2835, and 5630 strips up to approximately 6 meters, with stable current delivery that prevents flicker and color shift at the far end of the run.
• Surveillance Systems — Powers IP cameras, dome cameras, and NVR accessories; low ripple output (≤120mV) prevents image artifacts on analog and hybrid systems.
• Networking Equipment — Compatible with routers, switches, modems, and VoIP adapters requiring 24V DC input.
• 3D Printers & CNC — Provides stable power for control boards, hot-end heaters on entry-level machines, and stepper motor drivers.
• Industrial Controls — Suitable for PLC I/O modules, sensor arrays, and access control panels operating within the specified temperature range.
Four independent protection circuits in the 24V 3A Model operate autonomously to safeguard both the unit and connected equipment:
• Over-Voltage Protection (OVP) — Shuts down output if voltage exceeds safe threshold; auto-recovers when fault clears.
• Over-Current Protection (OCP) — Limits output current to prevent damage from overloaded downstream wiring.
• Short-Circuit Protection (SCP) — Instantly cuts output when a short circuit is detected.
• Over-Temperature Protection (OTP) — Thermal shutdown activates if internal temperature exceeds design limits; resumes once cooled.
All protection modes are non-latching — the model automatically restarts after the fault condition is removed. Full UL/CUL, FCC, CE, and CB certifications support compliance for commercial, industrial, and residential installations worldwide.
Every 24V 3A Model carries a 3-year warranty covering manufacturing defects. Technical support assists with compatibility verification, cable length selection, and connector configuration. OEM and ODM services are available for custom branding, cable lengths, and plug styles on bulk orders (MOQ 1000 pcs, 7–10 day lead time).
TQ Power manufactures AC/DC adapters ranging from 5W to 500W, with every unit undergoing 100% burn-in testing, hi-pot verification, and output regulation validation before shipping. ISO 9001 certified quality management and UL/CE/FCC/CB listings support worldwide distribution.

Frequently Asked Questions
What is a 24V 3A power supply used for?
This 72W adapter delivers 24V DC at up to 3A. It is most often used for 24V LED strip lighting (roughly 6 m of 5050 or 2835 strip), CCTV cameras and NVR accessories, networking equipment, 3D printer control boards, and industrial control panels.
Can this 24V 3A power adapter drive LED strips?
Yes. With 72W of output it drives about 6 m of 24V 5050 or 2835 LED strip at roughly 12W per meter. For longer runs, split the strip into multiple feeds or move up to a 120W model to avoid voltage drop and color shift at the far end.
What is the difference between a 24V 3A and a 24V 2A adapter?
Both output 24V DC, but the 3A version delivers 72W versus 48W. Choose the 3A model when your total load is between 48W and 72W, or when you want headroom for startup surges — a supply running at 70-80% of its rating lasts longer.
Does this 72W adapter work with both 110V and 220V?
Yes. The universal input accepts 100-240V AC, 47-63Hz, so it runs in North America, Europe, Asia and Australia without a converter. The AC plug type is customized to your market (US / EU / UK / AU).
What DC connector does this 24V 3A power supply use?
Standard 5.5 x 2.1 mm barrel jack, with 5.5 x 2.5 mm and other plugs available on request. The DC cable is 1.2 m by default, with 1.5 m and 2 m options for OEM orders.
Is this power supply UL listed?
Yes. The adapter is UL/CUL listed and also carries FCC, CE and CB certifications plus DoE Level VI efficiency, so it is accepted for commercial and residential installations in the US, EU, UK and Australia.
What is the MOQ and lead time for this 24V 3A adapter?
MOQ is 1000 pcs. Stock items ship in 7-10 days; OEM/ODM orders with custom plugs, labels or packaging take 15-25 days. Samples are available before mass production.
Can this 72W power supply run 24/7 continuously?
Yes. It is built for continuous duty with 105 degrees C rated capacitors and stays below 50 degrees C surface temperature at full load. OVP, OCP, SCP and OTP protections are non-latching and recover automatically once the fault clears.
Do you offer OEM/ODM customization?
Yes. As a manufacturer since 2011 we customize AC plug type, DC connector and cable length, logo printing and retail packaging, as well as other voltage/current combinations. Send us your spec and target quantity for a quote.
How much does a 24V 3A 72W power supply cost?
Factory-direct pricing starts at $3.88 for the standard model and $4.28 for the UL-certified version, depending on order quantity and customization. Request a quote for volume pricing.
