LDH-45B-350 Frequently Asked Questions (FAQs)

  • The maximum ambient temperature for the LDH-45B-350 is 70°C, but it can be derated to 50°C for high reliability applications.
  • No, the LDH-45B-350 requires natural convection cooling and should not be used in a sealed enclosure. Ensure good airflow around the power supply to prevent overheating.
  • The LDH-45B-350 requires a minimum load of 10% to maintain stability and regulation. Operating below this minimum load may cause the output voltage to drift or oscillate.
  • No, the LDH-45B-350 is not designed for parallel operation. Connecting multiple units in parallel may cause instability, oscillation, or even damage to the power supplies.
  • The LDH-45B-350 can withstand input surges up to 300Vac for 5 seconds, but repeated surges may reduce the power supply's lifespan.
