Overtemperature Thermal Shutdown, Over Voltage Protection & Derating
OT Over Temperature
The maximum ambient temperature is +70°C. If the
power Supply exceeds this value (over temperature protection) it completely
shuts down (metering point 50mm from outside device). The device restarts
automatically into operation when the temperature drops to a normal value.
OVP Over Voltage Protection
Exceeding the OVP results into ticker mode.
Resuming the failure causes automatic restart into normal operation. For the
values please read the Technical Table on page 2.
Baseplate Cooling & Temperature Management
The temperature management of the CPS-EC series provides a direct dissipation of the main energy losses.
The internal coolers of the output diodes and the power FETs connect to the back-plate cooler. It is possible to
dissipate about 40 – 50% of the energy losses out of a system while using the Baseplate cooling bundle
2201002001 to hard mount the unit to a plane and heat conductive surface.
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 with EN62368-1). The CPS-EC1500 models are to be operated with floating output when
connected in series. Such the output terminals must not be connected to earth (GND/PE). 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 & Decoupling
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-EC models have no internal O-ring diode, to operate the
devices redundant N+1.
Coating Option
We offer the CPS-EC series with an optional coating. It is to be used in e.g. dusty, dirty, high humidity area or in
awaiting quick temperature changes. Short circuit and corrosion at print board lines and at solder points can be
prevented. The coat itself is a transparent acrylic resin.
