Phihong’s Desktop Adapters, ranging from 15W to 300W (Models: AA, PPL, PSA, PSAA, PSAC, PSC, PSM), offer versatile power solutions. The Desktop Adapter Installation Manual provides a comprehensive guide to ensure a secure and efficient setup.

Installation Steps:

  1. Pre-Installation Checks: Before attaching the DC plug to equipment, unplug the adapter from AC power. Verify that the output connector, polarity, voltage, and current align with the equipment’s specifications.
  2. Linkage and Connection: Keep the linkage between the adapter and its power cord tight. Connect the DC plug to the device securely, holding both the plug and device during connection.
  3. Cable Protection: Safeguard input and output cables against mechanical stress and potential trampling.
  4. Ventilation and Clearance: Ensure proper device ventilation during use to prevent overheating. Maintain a 10-15cm clearance from other heat sources.
  5. Power Cord Standards: Use an approved power cord equal to or greater than SVT/SPT or H03VV-F for electrical safety.
  6. Long-Term Storage Precaution: If the end equipment won’t be used for an extended period, disconnect it from the power supply to prevent damage from voltage peaks or lightning strikes.
