November 17, 2000 PFC 500/E Instruction Manual 71
Appendix
A
Technical specifications and operating
limits
This appendix describes the PFC 500/E technical specifications, operating limits, and
shipping and storage requirements.
Technical specifications
Technical specifications include power requirement, size, drive, interface, and
standards information.
ac power requirements
The input current, power (VA), and dissipation per PFC 500/E are based on the
maximum capability of the power supplies and cooling system to provide internal
regulated power. Typical values will be less, depending on the number and
manufacturer of disk modules. These values represent either
• the values for the line cord of a PFC 500/E with a single power supply, or
• the total values shared by the line cords of two power supplies in the same iDAE,
with the division between the line cords and supplies at the current sharing ratio.
A failure of one of the two power supplies in the iDAE results in the remaining supply
and cord supporting the full load. You must use a rackmount cabinet with ac power
distribution, and have main branch ac distribution that can handle these values for
each iDAE in the cabinet.
Requirement Description

Power dissipation 392 W max estimate (fully configured)
Power factor 0.98 min at full load, low voltage
Heat dissipation 1411x10 3 J/hr (1340 BTU/hr) max estimate
In-rush current 25 A max estimate for 1/2 line cycle, per power supply
ac protection 8 A thermal circuit breaker on each power supply
ac inlet type IEC320-C14 appliance coupler
Hold-up time 20 ms min at 50 Hz
Current sharing 60% max, 40% min
