CHAPTER 1: ABOUT THE REDUNDANT POWER UNIT
Overview
This Redundant Power Unit (SMCRPU14) can supply 600 Watts of backup
power to four switches in the event of an AC loss or failure of an internal
power supply.
Features and Benefits
• Supports four switch units with 12 VDC supply of up to 150 W.
• Indicator LEDs located on the front panel.
• RPU AC line cord can draw power from a different supply circuit.
• DC line cords provide backup power to attached devices.
• Thermal overload protection prevents the RPU from overheating if a
thermal overload occurs.
• Over-voltage protection shuts down an output channel if the voltage
exceeds a preset threshold.
• Over-current protection shuts down the RPU if the output load
exceeds a preset threshold.
