Hold-up Time of CPD Models
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:

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.
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
addition, the total power from outputs Vo1, Vo2, and Vo3 is
limited to P
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

Note: We recommend connecting some capacitors parallel to

In all models, all outputs are monitored for an overvoltage
condition. If an overvoltage of 120 – 130% is dedected, the
converter is permanently disabled. To reset, the input
voltage must be removed for 10 – 20 seconds.
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
the measurement point of the case temperature T
Mechanical Data) will approach after an initial warm-up
phase the indicated maximum value of T
However, the relationship between T
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
