ThePSR1800-56A is an AC/DC-input and DC-output power module that provides a maximum output of1800 W. The PSR1800-56D is a DC-input and DC-output power module that provides a maximumoutput of 1800 W.The S9804 switch supports 1+1 power redundancy. The S9810 switch supports N+1 or N+N powerredundancy. N can be 1 or 2. The number of power modules that a switch requires is determined bythe power supply mode and system power consumption. Make sure the total maximum output powerof the installed power modules is greater than the system power consumption. H3C recommendsthat you reserve 20% of the maximum output power.Table 19 and Table 20 describe PSR1800-56A and PSR1800-56D power module specifications,respectively.Table 19 PSR1800-56A power module specificationsItem SpecificationRated input voltage range • 100 VAC to 240 VAC @ 50 Hz or 60 Hz (AC input)• 240 VDC (high voltage DC input)Maximum input current • 13 A (AC input)• 10.5 A (high voltage DC input)Output voltage –56 VDCOutput current• 32.2 A (201 VAC to 240 VAC input voltage)• 19.6 A (100 VAC to 200 VAC input voltage)• 32.2 A (240 VDC input voltage)Maximum output power• 1800 W (201 VAC to 240 VAC input voltage)• 1100 W (100 VAC to 200 VAC input voltage)• 1800 W (240 VDC input voltage)Operating temperature –10°C to +55°C (14°F to 131°F)Relative humidity 5% to 95%NOTE:You can install one power module if the input voltage is in the range of 200 VAC to 240 VAC. Youmust install two power modules if the input voltage is in the range of 100 VAC to 200 VAC.
