How to use

Connect the power supply to a compatible mains outlet using the integrated or supplied mains lead, then attach the DC output plug to the device requiring 12 V DC input. Confirm that the device's input voltage and required current do not exceed 12 V and 2.5 A respectively. After connection, power on the mains supply and verify the target device powers up correctly. If the device has polarity markings, ensure the adapter plug matches the required polarity before connection.

Usage recommendations

Use the adapter in well-ventilated indoor locations, avoid exposure to moisture and extreme temperatures, and ensure the DC plug fits securely. For devices with higher startup currents, verify that the 2.5 A rating is sufficient. If in doubt about compatibility or polarity, consult device documentation or a qualified technician.
