Use these guidelines to define the thresholds when each element needs to be considered.
• Voltage type—AC only.
• Voltage threshold—AC input voltages within 3 V of the minimum specified input volt-
• Significant current
• High ambient temperatures—If all three of the above factors are present, then look at
User’s Manual
age for Options 3 or 4, within 5 V of the minimum specified input voltage for Option 5.
Table D-1 to determine whether the operating temperature creates an issue. The capaci-
tor lifetimes are listed at the specified temperatures for the existing 1000 µF capacitor
at position C34 on the PowerCore module by itself and with an additional user-supplied
1000 µF capacitor installed between the DC+ line (from pin 4 of J4) and ground on the
motherboard:
more than 1 A to user circuits for 2 A regulator
more than 250 mA to user circuits for 1 A regulator
