Unregulated power supplies – Overview
Unregulated power supplies – compactPower
Compact power supply units are important links in the
power supplies for controllers. They are used where
processes or control voltages are required that vary from the
mains voltage. Transformers provide the electrical isolation
between the input circuit and the output circuit.
The minimum requirement (to VDE 0550) is 2,000 V.
Screw terminals secure the input-side connection to the
mains. The single-phase devices are rated for a nominal
voltage of ∼230 ± ∼15 V, or ∼400 V ± ∼15 V, 50/60 Hz,
the 3-phase devices for 3 x 400 V ± 5 %. The secondary
DC voltage from the transformer is conducted to a bridge
rectifier where it is rectified.

D.2
The pulsating DC voltage is then fed from the rectifier and
filtered to a low residual ripple by means of an electrolytic
capacitor.
This DC voltage is then fed to the output terminal. These
are designed as pluggable screw terminals. A varistor is
integrated in the output circuitry to attenuate voltage peaks.
The operating status is indicated by means of a green LED
via the output circuit. Devices with 600 W and higher are
equipped with a fan.

Adapted to standard voltages in accordance
with IEC 38
By choosing the appropriate terminals, the ± 15 V tapping
capability allows the single-phase devices to be connected
to six different nominal AC voltages: 215, 230, 245, 385,
400, 415 V.
The ± 5 % tapping capability allows the 3-phase devices to
be connected to three different nominal voltages: 380, 400,
415 V.
Reliable short-circuit and overload protection
Integrated on the secondary side in device sizes up to
CP NT 192 W, the FKS fuse protects against overloads
and shortcircuits. For the devices CP NT 264 W and
CP NT 432 W, this protection is achieved by means of a
thermostatic switch built into the transformer.

Easy mounting
Keyhole assembly simplifies mounting and saves time. A
snap-on fixing attachment for 35 mm DIN rails is available as
an accessory for single-phase devices up to 144 W.
Simply plugged into the device and secured with two
screws, it ensures easiest possible mounting!
