Napájací zdroj ALLNET AP002 / AP003-EU adaptér 5V 3A pre jednodoskové počítače a vstavané zariadenia

The ALLNET AP002 / AP003-EU power supply adapter provides a regulated 5V DC output at up to 3A, designed for powering single-board computers, small routers, IoT modules and other embedded devices. This compact EU plug adapter delivers stable voltage suitable for development boards and repair tasks where a reliable low-voltage supply is required. Its small footprint and industry-standard output make it a practical choice for bench use and field replacements.

Advantages

The adapter offers a consistent 5V output capable of supplying up to 3A, which covers most low-power SBCs and peripherals. Its compact EU-form factor simplifies installation in standard European outlets and reduces workspace clutter. Built-in regulation maintains stable DC output under typical load conditions, while common protection measures help guard connected devices against minor electrical faults. The straightforward design makes it simple to integrate into projects or use as a replacement power source for embedded systems.

Suitable for

• Single-board computers (SBCs) such as Raspberry Pi-class and other low-power boards
• Small routers, network modules and access points
• IoT modules, sensors and development kits
• Embedded devices, controllers and peripheral modules that require 5V/3A
• Repair, prototyping and bench testing of low-voltage electronics

Key specifications

• Output voltage: 5 V DC
• Maximum output current: 3 A
• Plug type: EU mains plug (compact form factor)
• Output connector: standard DC barrel or cable with fixed connector (as supplied)
• Regulation: built-in voltage regulation for stable DC output
• Intended use: indoor, mains-powered adapter for low-voltage embedded electronics

How to use

Connect the adapter to a compatible mains outlet and attach the output connector to the device’s 5V input, ensuring polarity and connector fit are correct. Verify that the device’s rated input matches 5V and that its current draw does not exceed 3A. Power the adapter only when the target device is wired correctly and observe any device-specific startup procedures. Disconnect the adapter from the mains before changing wiring or connectors.

Recommendations

Use the adapter in dry indoor environments and avoid exposure to moisture or extreme temperatures. If a device approaches the 3A limit under sustained load, consider a higher-current power supply to reduce stress on the adapter. Inspect the connector and cable periodically for wear; replace the adapter if any damage to insulation or connectors is visible. For sensitive electronics, confirm the connector polarity and, if necessary, use additional protection such as inline fuses or surge protection devices.
