JNP10K-PWR-AC2 Power Supply
The JNP10K-PWR-AC2 power supply is a high-capacity, high-line model that is designed to support
either AC or DC systems in either a low-power or high-power mode. The power supply takes AC input
and provides DC output of 12.3 VDC, 5000 W with a single feed and 5500 W with a dual feed. For AC
systems, the operating input voltage is 180 to 305 VAC and for DC systems, the operating input voltage
is 190 to 410 VDC.
The number of power feeds and whether the power supplies provide high output (30-A) or low output
(20-A) power is configured using a set of dual inline package (DIP) switches on the faceplate of the
power supply. If one power supply in the chassis is set to low power, the power budget for the chassis is
reduced to low power, regardless of their DIP switch settings or the output results in CLI. This design
safeguards against accidentally setting the power supply to 30-A in a facility that can only provide 20-A
and tripping the facility circuit breaker. We recommend that you do not mix DIP switch settings in your
system. See
Table 14 on page 52 .
