SHP650PS48-EF datasheet by XP Power

SHP650PS48-EF Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this power supply?
  The SHP650PS48-EF can operate from -20°C to +70°C, with derating above 50°C.
• How do I ensure the power supply is properly ventilated?
  The power supply requires a minimum of 1U (44.45mm) clearance above and below the unit for airflow. Ensure good airflow around the unit and avoid blocking the ventilation holes.
• What is the MTBF (Mean Time Between Failures) rating for this power supply?
  The SHP650PS48-EF has a calculated MTBF of 550,000 hours at 25°C, based on MIL-HDBK-217F.
• Can I use this power supply in a high-altitude environment?
  The SHP650PS48-EF is designed to operate up to 3,000 meters (10,000 feet) above sea level. Above this altitude, the power supply's performance may degrade.
• What is the power supply's behavior during a brownout or sag in the input voltage?
  The SHP650PS48-EF has a built-in undervoltage protection (UVP) that will shut down the output if the input voltage falls below 80% of the nominal input voltage.
