NOTE Heat dissipation is calculated using the PSU wattage rating.

NOTE This system is also designed to connect to the IT power systems with a phase to phase voltage not exceeding 240 V.

NOTE PSUs rated for 1100 W AC or 1100 W Mixed Mode HVDC and higher require high-line voltage (200–240 V AC) to supply their rated capacity.
