Open Collector Circuit Interface
Between all open collector outputs and the power output is a reinforced
isolation of max. 400Vdc and a basic isolation of max. 600Vdc working
voltage.
(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 (not applicable to EN62368-1). Due to the dielectric strength of the internal components used, only the
models with an output voltage of 48Vdc 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
To increase the overall power of the power supply, up to 5 units 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. Allow proper connection for low contact resistance. 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.
