SRS-4812 Frequently Asked Questions (FAQs)

  • The maximum capacitive load for the SRS-4812 is 470uF. Exceeding this value may cause instability or oscillation.
  • Yes, the SRS-4812 can be used in a redundant configuration, but it requires an external ORing diode and a redundant control circuit to ensure proper operation.
  • The minimum input voltage required for the SRS-4812 to start up is 1.5V below the nominal input voltage rating (e.g., 85V for the 100V input model).
  • The power derating for the SRS-4812 at high ambient temperatures can be calculated using the thermal derating curve provided in the datasheet. As a general rule, the output power should be derated by 2.5% for every 1°C above 40°C.
  • Yes, the SRS-4812 is designed to withstand high-vibration environments, but it's recommended to follow the vibration test specification in the datasheet and ensure proper mounting and screw tightening to prevent damage.
