24V 5A Power Supply 120W AC/DC Adapter

Product Details

Product Overview

The 24V 5A power supply is a 120W AC/DC adapter that converts a universal 100–240V input into a regulated 24V DC output. The desktop housing sits stable on a shelf or inside a cabinet, and the detachable AC cord simplifies replacement and regional variants. The unit meets DoE Level VI, the current standard for an efficient power supply, and carries UL listing with FCC and CE certification. Four independent protections (OVP, OCP, SCP, OTP) keep both the adapter and the connected load safe during continuous operation.

Design & Build Quality

This 24V 5A power supply is built in our own factory around a high-frequency switching topology and 105°C-rated electrolytic capacitors, reaching up to 88% efficiency under DoE Level VI. As a 120W desktop adapter, it keeps case temperature below 50°C at continuous full load, so it can sit in cabinets, racks and enclosures with limited airflow. The fanless, vent-free housing runs silent and blocks dust — a practical choice for office, studio and light industrial installations. UL listed versions are available for North American projects.

Typical Applications

With 120W of continuous output, the 24V 5A adapter covers multi-device 24V installations. It also works as a drop-in replacement for a failed 24V 5A AC adapter or DC adapter rated at 5000mA. • LED strip lighting — up to about 8 m of 24V 5050 strip, with 24V reducing voltage drop on long runs. • CCTV clusters — a group of 24V cameras, video intercoms and access controllers through a distribution box. • Passive PoE injectors — supplies several 24V passive PoE injectors for wireless APs and point-to-point links. • Audio and display — compact amplifiers, mixers, digital signage players and kiosk displays. • Industrial controls and test racks — PLC modules, sensor arrays, relay banks and aging fixtures.

Four independent protection circuits in the 48V 1.5A 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 5A 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 500 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.
