Instructions for Use:

  1. Mounting:

    • Ensure that the diode bridge is mounted on a heat sink if operating at high currents to maintain junction temperature within safe limits.
    • Use thermal compound between the diode bridge and the heat sink to improve thermal conductivity.
  2. Electrical Connections:

    • Connect the AC input to the two input terminals (typically marked as ~ or 1 and 3).
    • Connect the DC output to the positive (marked + or 2) and negative (marked - or 4) terminals.
  3. Surge Current Handling:

    • The diode bridge can handle peak surge currents up to 120 A for short durations (8.3 ms single half sine wave). Ensure that the surge current does not exceed this limit to avoid damage.
  4. Thermal Management:

    • Monitor the temperature of the diode bridge during operation. If the temperature exceeds the maximum junction temperature, reduce the load or improve cooling.
  5. Storage:

    • Store the diode bridge in a dry, cool place within the storage temperature range (-65°C to +175°C).
  6. Handling:

    • Handle the diode bridge with care to avoid mechanical damage. Do not apply excessive force to the leads.
  7. Testing:

    • Before installation, test the diode bridge using a multimeter to ensure it is functioning correctly. Check for continuity between the appropriate terminals.
  8. Compliance:

    • Ensure that the diode bridge meets all relevant safety and regulatory standards for your application.
