5.1.2
Backplane
Backplanes to be used with the CP6003-SA must be adequately specified. The backplane
must provide optimal power distribution for the +3.3 V, +5 V and +12 V power inputs.
Input power connections to the backplane itself should be carefully specified to ensure a mini-
mum of power loss and to guarantee operational stability. Long input lines, under-dimensioned
cabling or bridges, high resistance connections, etc. must be avoided. It is recommended to
use POSITRONIC or M-type connector backplanes and power supplies where possible.
5.1.3
Power Supply Units
Power supplies for the CP6003-SA must be specified with enough reserve for the remaining
system consumption. In order to guarantee a stable functionality of the system, it is recom-
mended to provide more power than the system requires. An industrial power supply unit
should be able to provide at least twice as much power as the entire system requires.
As the design of the CP6003-SA has been optimized for minimal power consumption, the pow-
er supply unit shall be stable even without minimum load.
Where possible, power supplies which support voltage sensing should be used. Depending on
the system configuration this may require an appropriate backplane. The power supply should
be sufficient to allow for backplane input line resistance variations due to temperature changes,
etc.
5.1.3.1
Start-Up Requirement
Power supplies must comply with the following guidelines, in order to be used with the CP6003-
SA:
•
Beginning at 10% of the nominal output voltage, the voltage must rise within
> 0.1 ms to < 20 ms to the specified regulation range of the voltage. Typically:
> 5 ms to < 15 ms.
•
There must be a smooth and continuous ramp of each DC output voltage from
10% to 90% of the regulation band.
•
The slope of the turn-on waveform shall be a positive, almost linear voltage increase and
have a value from 0 V to nominal Vout.
5.1.3.2
Power-Up Sequence
The +5 VDC output level must always be equal to or higher than the +3.3 VDC output during
power-up and normal operation.
Both voltages must reach their minimum in-regulation level not later than 20 ms after the output
power ramp start.
