Appendix A Power Supply Specifications
2700 W AC-Input and DC-Input Power Supplies
Power supply output capacity • 1350 W maximum (100–120 VAC)
• 2700 W maximum (200–240 VAC)
• 1350 W maximum (–48 to –60 VDC, with one DC
input)
• 2700 W maximum (–48 to –60 VDC, with two DC
inputs)
System power dissipation
• 3.4 KVA (high-line operation; AC-input)
• 3.5 KW (DC-input)
DC-input voltage –48 VDC to –60 VDC continuous
DC-input current (per DC input)
• 43 A @ –40.5 VDC

Note For multiple DC input power supplies, each
DC input must be protected by a dedicated
circuit breaker or a fuse. The circuit breaker or
the fuse must be sized according to the power
supply input power rating and any local or
national electrical code requirements.
