The DC power supply provides the following features:
•Input Overload Protection
As shown in Figure 1‐1 on page 1‐2, the power supply has a 50A circuit breaker on the front panel, to protect against internal damage due to a catastrophic failure.
•Redundancy
A maximum of six supplies can be operated in parallel, sharing a common power bus. Failure of any single supply will not affect operation of the power bus. In addition, inadvertent hot‐swapping of energized power supplies will not affect bus operation. This applies to all outputs of the power supply.
•Reverse Polarity Protection and Alarm
No damage will occur to the power supply if the input voltage is inadvertently reversed. An audible alarm will sound upon reverse polarity.
•Visual Indicators
As shown in Figure 1‐1 on page 1‐2, the power supply has two LEDs on the front panel. The PWR‐IN LED lights green when the input voltage is above the minimum required to operate. The PWR‐OUT LED lights green if all power supply voltage outputs are in regulation.
