PFC 500/E Instruction Manual

Appendix
A
Technical specifications and operating
limits
This appendix describes the PFC500/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 PFC500/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 an PFC500/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.
