Temperature Monitoring & Derating
The maximum ambient temperature during operation is +
60°C. If the overtemperature protection is activated, the
power supply but not the fan is switched off.
The measuring point is 10mm outside the power supply.
The power supply unit starts automatically when it has
cooled down.
Open Collector Circuit Interface Z3.3
Between all open collector outputs and the power input and the power output
is a reinforced Insulation of max. 400Vdc.
(Note: this applies to all signals from CON1 and CON2, regardless of whether
they are designed as open collector, or not)
Series Operation
Two or more units of the same model and output voltage can be operated up to a total voltage of 600Vdc in
series. Due to the dielectric strength of the internal components used, only the models with an output voltage of
90Vdc and later are approved for series operation. Other power supplies are not approved for series operation
above 60Vdc.
If the units are remotely controlled via the analog interface it is compulsory to use a potential-free control
voltage!
Parallel Operation & N+1 Decoupling
In order to increase the overall power of the power supply, two or more devices of the same model with the
same output voltage may be operated in parallel. We recommend using a busbar for the DC power connector.
Make sure that the cable lengths and cable cross-sections of all power supplies to the busbar or to the star
point are identical. If you want to use the sensing function, connect it also to the star point or busbar. To avoid
measurement errors, select the line length from the neutral point or from the busbar to the load as short as
possible and use the maximum possible conductor cross-section.
The CPS-EX models have no internal O-ring diode, to operate the devices N+1 redundant.
