Description
These extremely compact DC-DC converters incorporate all
necessary input and output filters, signaling and protection
features, which are required in the majority of applications. The
converters provide important advantages such as flexible
output power through primary current limitation, high efficiency,
excellent reliability, very low ripple and RFI noise levels, full
input to output isolation, negligible inrush current, over-
temperature protection, and input over-/undervoltage lockout.
The converter inputs are protected against surges and
transients occurring on the source lines.
The converters are particularly suitable for rugged environ-
ment, such as railway applications. They have been designed
in accordance with the European railway standards EN 50155
and EN 50121-3-2. All printed circuit boards are coated with a
protective lacquer.
The outputs are continuously open- and short-circuit proof. An
isolated output Power Good signal and LEDs at the front panel
indicate the status of the converter. Test sockets at the front
panel allow for a check of the main output voltage.
Full system flexibility and n+1 redundant operating mode are
possible due to virtually unrestricted series or parallel con-
nection capabilities of all outputs. In parallel connection of
several converters, automatic current sharing is provided by a
single-wire interconnection.
As a modular power supply or as part of a distributed power
supply system, the extremely low-profile design reduces the
necessary power supply volume without sacrificing high
reliability. A temperature sensor disables the outputs when the
case temperature exceeds the limit. The outputs are
automatically re-enabled, when the temperature drops.
The fully enclosed, black-coated aluminum case acts as a heat
sink and an RFI shield. The converters are designed for 19"
DIN-rack systems occupying 3 U / 4 TE only, but can also be
chassis-mounted by four screws. Fitting an additional heat
sink or ordering options with fitted heat sink is possible as well.

Can anyone give me the circuit diagram of the voice-controlled and touch-sensitive lights used in the current building?
Please give me the circuit diagram. It would be best if you can write down the model of the sensor and the model of the chip used. The most important thing is the circuit diagram! ! Thank you!...
