Power Adapter Mikrotik APA-1 100W Black

The Mikrotik APA-1 100W Black is an auto power adapter designed to provide a stable 48V output and up to 100W of power in a compact 86 × 16 × 31 mm housing. It integrates multiple protective layers to guard connected equipment from voltage transients and incorrect polarity, and its jumper-selectable output or pass-through mode allows flexible use within MikroTik installations and other 48V systems.

Advantages

The adapter combines a gas-discharge tube and a TVS (transient voltage suppressor) semiconductor to suppress high-voltage spikes. Active polarity protection prevents damage if power is connected in reverse. An integrated low-pass filter reduces unwanted electrical impulses, and a standard fuse provides additional safety. The output voltage is adjustable by jumper position and a pass-through mode is available when input regulation is not required.

Suitable for

• Powering MikroTik routers, switches and other 48V network devices
• Automotive or mobile installations where voltage spikes may occur
• Environments requiring compact power adapters with built-in surge and polarity protection

Key specifications

• Brand: MikroTik
• Model: APA-1
• Output power: 100W
• Nominal output voltage: 48V (jumper-selectable; pass-through mode available)
• Colour: Black
• Dimensions: 86 mm × 16 mm × 31 mm

How to use

Install the APA-1 in-line with the power feed to the device and set the output voltage using the jumper according to the connected device requirements. If regulation is not needed, switch to pass-through mode. Connect input and output connectors following the product wiring diagram and ensure the fuse is appropriate for the application. The unit’s built-in protections operate automatically to suppress transients and prevent damage from reverse polarity.

Recommendations

For reliable operation, verify jumper position before connecting sensitive equipment, use the adapter within its rated power limits (100W), and replace the standard fuse with an equivalent value if blown. In automotive or harsh environments, check grounding and cable quality to reduce the chance of severe voltage spikes.
