Napájací zdroj ALLNET 12V 2,5A model 003920441, DC adaptér pre sieťové zariadenia

ALLNET 12V 2.5A power supply (DC adapter) provides a regulated 12-volt output with a maximum current of 2.5 amps designed for powering network devices and small electronics. The compact adapter delivers stable voltage and adequate current for continuous operation of routers, switches, access points and other equipment that require a 12V/2.5A input. This adapter can serve as a direct replacement for compatible power supplies or as a spare unit to ensure uninterrupted device availability.

Advantages

The adapter offers stable DC output to minimize voltage fluctuation and protect connected devices from power irregularities. Its compact form factor and standard DC barrel connector make installation straightforward in constrained spaces or rack setups. Built-in protection features such as short-circuit and overload prevention help reduce the risk of damage to both the adapter and the connected device. The adapter is intended for indoor use and is suited to continuous operation under normal ambient conditions.

Suitable for

• Routers and wireless access points that require 12V DC at up to 2.5A
• Small Ethernet switches and POE splitters with a compatible input
• Network peripherals, media converters, and other small electronics with matching voltage and current needs
• Replacement or spare power source for home and small office network equipment

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 2.5 A
• Output power: up to 30 W
• Connector type: standard DC barrel connector (check device polarity and plug size before use)
• Intended use: indoor, continuous operation for network devices and small electronics

How to use

Confirm that the device to be powered requires 12V DC and does not exceed 2.5A current draw. Verify the DC plug polarity and size match the device input. Connect the adapter plug to the device power input, then plug the AC side into a compatible mains outlet. Power the device on and verify correct operation. If the device does not power up, disconnect and re-check voltage, polarity and connector compatibility. Do not use the adapter if the device’s required current or voltage differs from the adapter’s specifications.

Recommendations

Use the adapter in a well-ventilated, dry indoor environment and avoid covering it to prevent overheating. If long cable runs are required, ensure voltage drop does not reduce delivered voltage below the device’s minimum requirement. Replace the adapter if it shows signs of damage, unusual noise or excessive heat. Keep the adapter away from moisture and unqualified repair attempts.
