Platinum 4100 BTU/hr 50/60 Hz 100–240 V AC and 200–380 V DC
1100 W AC Platinum 4100 BTU/hr 50/60 Hz 100–240 V AC, autoranging
1600 W AC 6000 BTU/hr 50/60 Hz 100–240 V AC, autoranging
NOTE: If a system with 1100 W AC or HVDC PSU operates from 100 to 120V, the power rating per PSU is derated to 1050 W.
NOTE: If a system with 1600 W PSUs operates from 100 to 120 V, then the power rating per PSU is derated to 800 W.
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 230 V.
NOTE: PSUs rated for 1600 W and higher require high-line voltage (200-240 V) to supply their rated capacity.
