Description
The S Series AC-DC and DC-DC converters represents a broad
and flexible range of power supplies for use in advanced
electronic systems. Features include high efficiency, high
reliability, low output voltage noise and excellent dynamic
response to load/line changes. LS models can be powered by
DC or AC with a wide-input frequency range (without PFC).
The converter inputs are protected against surges and
transients. An input over- and undervoltage lockout circuitry
disables the outputs if the input voltage is outside of the
specified range. Certain types include an inrush current limiter
preventing circuit breakers and fuses from tripping at switch-on.
All outputs are open- and short-circuit proof and are protected
against overvoltages by means of built-in suppressor diodes.
The outputs can be inhibited by a logic signal applied to pin 18
(i). If the inhibit function is not used, pin 18 must be connected
with pin 14 to enable the outputs.
LED indicators display the status of the converter and allow for
visual monitoring of the system at any time.
Full input-to-output, input-to-case, output-to-case and output-to-
output isolation is provided. The converters are designed and
built according to the international safety standards IEC/EN
60950 and EN50155. They have been approved by the safety
agencies TÜV and UL (for USA and Canada).
The case design allows operation at nominal load up to 71 °C in a
free-air ambient temperature. If forced cooling is provided, the
ambient temperature may exceed 71 °C, but the case temperature
must remain below 95 °C under all conditions.
A temperature sensor generates an inhibit signal, which disables
the outputs if the case temperature
Tc
exceeds the limit. The
outputs are automatically re-enabled when the temperature drops
below the limit.
Various options are available to adapt the converters to individual
applications.
The converters may either be plugged into a 19" rack system
according to IEC 60297-3, or be chassis mounted. They are ideally
suited for Railway applications.
Important:
For applications requiring compliance with IEC/EN
61000-3-2 (harmonic distortion), please use our LS4000 and LS5000
Series with incorporated power factor correction (PFC).

S Series Data Sheet
100 Watt AC-DC and DC-DC Converters
Functional Description
The input voltage is fed via an input fuse, an input filter, a bridge
rectifier (LS), and an inrush current limiter to the input capacitor.
This capacitor sources a single transistor forward converter.
Each output is powered by a separate secondary winding of the
main transformer. The resultant voltages are rectified and their
ripple smoothed by a power choke and output filter. The control
logic senses the main output voltage
V
o1 and generates, with
respect to the maximum admissible output currents, the control
signal for the primary switching transistor.
The second output of double-output models is controlled by the
main output but has independent current limiting. If the main output
is driven into current limitation, the second output voltage will fall as
well and vice versa.

Input Transient Protection
A suppressor diode and/or a VDR (depending on input voltage
range) together with the input fuse and a symmetrical input filter
form an effective protection against high input transient voltages
which typically occur in most installations, but especially in
battery-driven mobile applications.
Nominal battery voltages in use are: 12, 24, 36, 48, 60, 72, 110,
and 220 V. In most cases each nominal value is specified in a
APR 26, 2006 revised to SEP 25, 2006
tolerance of –30% to 25%.
In certain applications, surges according to RIA 12 are
specified in addition to those defined in IEC 60571-1. The
power supply must not switch off during these surges and
since their energy can practically not be absorbed an
extremely wide input range is required. The ES input range
for 110 V batteries has been designed and tested to meet
this requirement.
