HSEUREG04801(R2) MANUAL
Temperature Derating
The maximum ambient temperature during operation is + 70°C. If the over
temperature protection is activated, the power supply is switched off.
The measuring point is 50mm outside the power supply. The power supply
unit starts automatically when it has cooled down.
Series Operation
Two or more units of the same model and output voltage can be operated up to a total voltage of 240Vdc 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 analogue 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, 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. 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 HSEUREG models have no internal O-ring diode, to operate the
devices N+1 redundant.
Coating Option
We offer the HSEUREG-series with optional coating. It is to be used in e.g., dusty, dirty, high humidity, 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. Peters SL 1306 N-FLZ (transparent) IEC60216-1 2001,

Electrical Safety (Factory-Test / Field-Test Owner)
¹)
≥
90Vdc= 2000Vdc
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.
