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.
Parallel Operation & Decoupling
To increase the output power up to 5pcs of the CPS-EC units can be parallel
connected. Advise using busbars to connect several devices in parallel. Always
use identical cabling length and identical cross sections to the busbar or a star
point. When sensing is required, we recommend connecting the sense lines to
a star point located very close to the load. To avoid erroneous measuring the
cable section from the star point to the load shall be as large and as short as
possible.
The CPS-EC models have no internal O-ring diode. For decoupling devices
N+1. Up to 125Vdc we recommend using our RED00202 DIN rail diode module.
It is capable to decouple 2pcs of the CPS-EC power supplies from each other.
To increase the power capability RED models can be connected in parallel. For
higher voltages, an external decoupling diode shall be installed from the system
engineer.
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.

Electrical Safety (Factory-Test / Field-Test Owner)
¹)
≥
48Vdc= 2500Vdc
Type and factory test are the manufacturer. While repeating damage can
happen to the power supply unit. For the field test (owner) follow the below instruction:
a)
Use suitable test equipment, raising the voltage slowly
b)
Short circuit L1 and N, and all the DC output terminals.
c)
Use only test voltages of 50/60Hz. The outputs are unearthed and
therefore they have no resistance to GND/PE.
d)
If the residual voltage is
≥
60Vdc, observe the safety standards.
Use only specially insulated screwdriver to trim the Ua/Ia.
