✅ Confirmed Compatibility

Compatibility is limited to systems factory-configured for the 1100W −48 to −60V DC power option. The chassis must have the matching hot-plug PSU bay, power-distribution hardware and DC input wiring. A model name alone does not guarantee compatibility.

⚙️ Fit Notes

• This is a DC-input power supply. It does not accept 100–240V AC power.
• A standard IEC C13, C14, C19 or C20 power cable cannot be connected to this unit.
• The input requires a 6RYJ9 terminal block or an approved equivalent mating connector.
• Installation requires an electrically isolated and reliably grounded −48 to −60V DC SELV source.
• Source and return wiring must use 10-AWG copper conductors rated for at least 90°C.
• Maximum recommended conductor length is 2 meters.
• The DC branch circuit requires 50A overcurrent protection with a high DC interrupt rating.
• Use black wire for the negative −48/−60V source, red wire for DC return and green/yellow wire for safety ground.
• Reversing input polarity may permanently damage the power supply or system.
• DC input wiring should be completed by a qualified electrician or properly trained service technician.
• Never mix AC-input and DC-input power supplies in the same system.
• When multiple PSUs are installed, they must be the same input type and maximum output wattage.
• R520 and R620 systems configured for the 1100W option require both PSU bays to be populated.
• R720 and R720xd systems support two matching supplies in a 1+1 redundant configuration.
• R920 systems may support as many as four matching 1100W DC modules.
• Hot replacement is permitted only when the system is operating in a supported redundant configuration and the applicable service procedure is followed.
• Not compatible with PowerEdge T320 or T420. Those systems’ service documentation specifies AC power supplies.
