Hold-upTimeofCPDModels
For extended hold-up time of CPD models, use external
output capacitors or decoupling diodes and input capacitors
of adequate size.
Formula for additional external input capacitor:
2 ? P o ? ( t h total – t h ) ? 100
η ? ( V ti – V i min )
whereas:
C i ext = external input capacitance [mF]
P o = output power [W]
h = efficiency [%]
t h total = total hold-up time [ms]
t h = hold-up time [ms]
V i min = minimum input voltage [V]
V ti = threshold level [V]
Note : After V i was removed, the outputs maintain their voltage
for the time t h . Even if V i comes back during t h , but after t h , the
output voltage might be affected.
Redundant Operation and Hot Swap
Due to the integrated ORing FETs/diodes, the converters are
designed to be operated in redundant systems.
Hot swap is also possible, but the output voltages of each
bus may deviate dynamically by ≤ 5% during the plug-in / plug-
out operation.
condition. If an overvoltage of 120 – 130% is detected, the
converter is permanently disabled. To reset, the input voltage
must be removed for 10 – 20 seconds.
Note : The models CPA500/550 with version number before
V110 need approx. 60 s to recover.
Thermal Considerations and Protection
If a converter is mounted in the upright position with airflow as
specified in the general conditions of the tables 4 and 5,
allowing unrestricted forced-air cooling, and is operated at its
nominal input voltage and power at maximum ambient
temperature T A max (see Temperatures ), the temperature at the
measurement point of the case temperature T C (see
Mechanical Data ) will approach after an initial warm-up
phase the indicated maximum value of T C max (105 °C).
However, the relationship between T A and T C depends heavily
on the operating conditions and the system integration. The
thermal conditions are significantly influenced by the input
voltage, the output current, the airflow, and the temperature of
the adjacent elements and surfaces. T A max is therefore,
contrary to T C max , an indicative value only.
Caution : The installer must ensure that under all operating
conditions T C remains within the limits shown in the diagrams
fig. 4.
P o / P o nom
Note : We recommend connecting some capacitors parallel to
the bus to limit voltage deviations during hot swapping and

during switch-on / switch-off of the input voltage of one of the
parallel-connected converters.
Output Characteristic and Protection
All outputs are fully protected against continuous open-circuit
(no load) and continuous short-circuit conditions.
All outputs of CPx200/250 models have a constant current
limitation with a rectangular characteristic; see figure 3. In

between these outputs. Output Vo4 is disabled in the case of
overtemperature generated by overcurrent.
In CPA500/550 and CPD500 models, the total power of all
four outputs is limited to P o max .
In all models, all outputs are monitored for an overvoltage
