    1 Introduction 1.1 Overview The R50-5500E4 Power Supply Unit provides load power and battery recharge current (if applicable) during normal operating conditions. The Power Supply Unit is rated at its maximum output power 5500W. This means that, within the normal operating ambient temperature range and input voltage range, the maximum available output power is 5500W.
  • Page 8 WARNING! The module is rated for continuous operation at full output power up to +45°C (+113°F). Operation between +45°C (+113°F) and +65°C (+149°F) is considered abnormal and should be used on a temporary basis only. Proprietary and Confidential © 2025 Vertiv Group Corp.
