Power supply ALLNET ALL48V1A — 48 V DC, 1 A output, external adapter

The ALLNET ALL48V1A power supply is an external adapter that provides a stable 48 V DC output at up to 1 A. Designed for compact desktop or rack-side placement, this adapter is intended to power compatible networking equipment and other low-power devices that require a dedicated 48 V supply. The unit offers a straightforward connection for systems such as switches, routers and PoE injectors where a reliable external power source is needed.

Advantages

This external adapter delivers a regulated 48 V DC output with a maximum current of 1 A, ensuring consistent voltage for connected devices. Its compact form factor makes it suitable for installation in constrained spaces near networking hardware. The design emphasizes practical, direct replacement or addition of a dedicated power source for devices that do not have internal supplies or require an external adapter for installation flexibility.

Suitable for

• Powering small network switches and routers that accept 48 V DC input
• Supplying PoE injectors and inline power devices rated for 48 V
• Providing external power to low-power telecommunication and networking modules
• Replacing or adding a dedicated 48 V adapter in desktop or rack-side setups

Key specifications

• Output voltage: 48 V DC
• Maximum output current: 1 A
• Output power: up to 48 W (nominal: 48 V × 1 A = 48 W)
• Form factor: external desktop/rack-side adapter
• Application: designed for networking equipment and low-power devices requiring 48 V

How to use

Connect the adapter to an appropriate AC mains outlet using the supplied or compatible power cord, then attach the DC output plug to the device's power input jack that accepts 48 V DC. Verify polarity and connector compatibility before powering the device. Power the adapter only after all connections are secure and ensure the connected device's input specifications match the adapter's 48 V, 1 A output rating.

Recommendations

Use the adapter indoors in a dry, ventilated environment and avoid covering it during operation to prevent overheating. Confirm that the target device's voltage and current requirements are compatible with a 48 V, 1 A supply; if a device requires higher current or different voltage, select an appropriate power source. Periodically inspect the adapter, cable and connector for damage and replace if any wear or defects are found.
