Product Details
Product Overview
The 24V 3A power supply delivers a regulated 72W output from a universal 100–240V AC input, in a compact wall-mount housing that plugs directly into a standard outlet. A 5.5 × 2.1 mm DC barrel connector mates with most 24V equipment, and the 1.2 m output cable reaches cabinets, racks and ceiling-mounted devices without an extension.
Efficiency meets DoE Level VI, and four independent protections (OVP, OCP, SCP, OTP) guard both the adapter and the connected load. The fanless, vent-free design runs silent and is suitable for continuous 24/7 operation in offices, studios and light industrial enclosures.

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, the 24V 3A adapter covers a wide range of 24V DC loads:
LED strip lighting — drives 24V 5050 and COB strips up to about 5 m, with stable output that prevents flicker at the far end.
CCTV and access control — powers 24V cameras, video intercoms and electric locks, with low ripple for clean video.
Networking equipment — routers, switches, media converters and small PoE injectors requiring 24V DC.
3D printers and CNC — a stable 24V rail for control boards, hotends up to 40W, fans and stepper drivers.
Industrial controls — PLC I/O modules, sensors, relays and solenoid valves.
Safety & Protection
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.
Warranty & Technical Support
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).
