CPX8216 and CPX8216T Installation and Use (6806800A52C)
Appendix A Specifications
134
DC Input DC Voltage: -36 Vdc to -72 Vdc (autoranging)
Turn-on Threshold: -38.5 Vdc to -41Vdc
Turn-on Surge Current: 20 Amps at -36 Vdc maximum in less than 4 msec.
Efficiency: 70% minimum at full load and nominal line, including output Oring diodes
Input Current: Measured 13A @ -48 Vdc at 475W
Output All measurements are made at the output connector of the power supply. The power
supply is used in an N+1 power system. Each voltage output supports power sharing.
Minimum Load Operation: None
Total Regulation: Total regulation is any combination of line, load and cross
regulation, actual set point (as a deviation from the nominal set point), warm up, and
temperature that results in an output voltage that deviates from the nominal set point.
Table A-1 provides the total regulation for each output:

Output Power 400 Watts total continuous maximum from all outputs. Any mix of outputs
totaling 400W is acceptable.
DC Output Voltage
Adjustment
No output adjustments.
Output Noise Total periodic and random deviation (PARD) noise found on outputs of the
power module shall be, as measured at the backplane:
-From 0 to 30 MHz bandwidth for ripple <50 mV
-From 0 to 100 MHz bandwidth for spikes <75 mV
Overload Protection All DC outputs have a method to protect the power supply from overloads
and shorts. When one output is overloaded, then all outputs are turned off.
Cycling the AC or DC input off then on will cause the power supply to
attempt recovery.
Output to Output Short
Protection
The power supply provides protection when any output is shorted to any
other output. A short is considered to be any interconnection that results
in any output deviating from its regulation range by more than 0.7 Volts.
Cycling the AC or DC input off then on will cause the power supply to
attempt recovery.
