48V 1.5A Power Supply 72W AC/DC Adapter

Product Overview

The 48V 1.5A Desktop Power Adapter is a robust and efficient power supply engineered for high-voltage, mid-to-high power electronic devices. With universal AC input (100-240V) and a stable 72W DC output, it works seamlessly across North America, Europe, Asia, and beyond. The adapter features a detachable AC power cord with a standard C8 or C14 connector, allowing users to easily replace the cord for different regional outlets. It comes with a standard 2.1/5.5mm DC output connector, making it compatible with PoE network switches, industrial controls, communication equipment, electric bike chargers, and many other 48V devices.

The aluminum alloy housing provides excellent heat dissipation without the need for a fan, making it ideal for noise-sensitive installations. The compact form factor (115*50*32mm) makes it ideal for space-constrained desktop and cabinet installations.

Wide Applications

This 48V 1.5A desktop power adapter is designed for versatile use. It powers PoE network switches, industrial control systems, communication equipment, electric bike chargers, and many other 48V devices. The stable 48V output ensures clean power for sensitive electronics, providing a long-lasting and reliable solution for home, office, and industrial applications.

The product label clearly displays all technical parameters and safety certification marks. Each unit is individually tested and serialized for full traceability. The UL, CE, and FCC certifications ensure compliance with international safety standards for global market distribution.

Safety Features

Built-in protection circuitry includes Over-Voltage Protection (OVP), Over-Current Protection (OCP), Short-Circuit Protection (SCP), and Over-Temperature Protection (OTP). In the event of a fault, the power supply enters safe mode and automatically recovers once the fault clears—no manual reset required.
