3.6.1
Power Supply Module Efficiency
The following table provides the required minimum efficiency level at various loading conditions.
These are provided at three different load levels: 100%, 50%, and 20%. The input voltage is set
to -53VDC during the test.

DC Inlet Connector
The power supply has the -48VDC input fused. The fusing is acceptable for all safety agency
requirements. The DC inrush current does not cause the fuse to blow under any conditions. No
protection circuits in the power supply will cause the DC fuse to blow unless a component in the
power supply has failed. This includes DC output load short conditions.

DC Input Voltage Specification
The power supply operates within all specified limits over the following input voltage range.

DC Holdup/Dropout Time
During a DC dropout of 0.2ms or less the power supply meets dynamic voltage regulation
requirements for every rated load condition. A DC line dropout of 0.2ms or less does not cause
tripping of control signals or protection circuits. Repeated every 10 seconds starting at the min
input voltage DC line dropout does not damage the power supply under any specified load
conditions. The PWOK signal does not go to a low state under these conditions. DC dropout
transients in excess of 0.2 milliseconds may cause shutdown of the PS or out of regulation
conditions, but do not damage the power supply. The power supply recovers and meets all turn
on requirements for DC dropouts that last longer than 0.2ms. The power supply meets the DC
dropout requirement over rated DC voltages and output loading conditions.
