Pro Disk Network Buyer’s Guide: Power Supplies & Power Protection
PSU Sizing: Connected Load, Efficiency Curves, and N+1 Redundancy
For racks with shared PDUs, plan PDU capacity at 80% of breaker rating, not 100%. A 30A PDU should carry no more than 24A sustained. Distribute high-power chassis across multiple PDUs in dual-feed racks so a single PDU failure does not exceed the survivor's headroom.
AC Input, Phase Balancing, and Datacentre Power Best Practices
The RG5-4357-E accepts a defined AC voltage range, typically 100-240V or 200-240V for high-output server PSUs. Higher voltage = higher efficiency: a server PSU at 240V input runs 1-2% more efficient than the same PSU at 120V. In datacentres with 208V three-phase, balance loads across the three phases to avoid neutral saturation and reduce harmonic distortion on the upstream UPS.
