Heat dissipation (thermal/output):		1126 BTU/hr	1195 BTU/hr
Hold-up time:		20 ms	20 ms
	DC Output Power Ratings
Max. output power (combined):		850 W (760 W + 90 W fans)	1400 W (1310 W + 90 W
			fans)
Non-PoE:		3.3 VDC @ 150 A	3.3 VDC @ 150 A
		12 VDC @ 65 A	12 VDC @ 65 A
PoE:		50 VDC @ 18 A	50 VDC @ 18 A
Fans:		12 VDC @ 7.5 A	12VDC @ 7.5 A

Note the following information:

•The maximum steady-state output power is limited to a total of 850 W for any combination of output voltages/currents at low-line 100-120 VAC nominal input voltage conditions.

•The maximum steady-state output power is limited to a total of 625 W for any combination of output voltages/currents, excluding the 50 VDC source at low-line 100-120VAC nominal input voltage conditions. This limitation is required to ensure that there is sufficient PoE power or 225 W total at this input voltage condition.

•The maximum steady-state output power is limited to a total of 950 W for any combination of output voltages/currents, excluding the 50 VDC source at high-line 200-240VAC nominal input voltage conditions. This limitation is required to ensure maximum PoE power or 450 W total for the 50 VDC source at this input voltage condition.

•To obtain the full output power rating of 1400 W, you must connect the power supply to a nominal (200-240VAC) input voltage source.
