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 10mm 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 analog interface it is compulsory to use a potential-free control
voltage!
Parallel Operati
on & 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 HSEUREG models have no internal O-ring diode, to operate
the devices N+1 redundant.
Isolating Transformer 1:1 ADTW201
for galvanic isolation
(external optional device)
The isolating transformer is used to galvanic isolate impressed current. The device is self-powered. The input to
output ratio is 1:1. We recommend to use the isolation transformer for all units above 60Vdc output voltage until
the system integrator did not approve other arrangement to meet national safety requirements.
Coating
Option
We offer the USEureg-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,
