Features
• Input voltage up to 144 VDC
• Single output of 3.3 to 48 VDC
• No input-to-output isolation
Description
• High efficiency up to 97%
The PSC and PSL Series positive switching regulators are
designed as power supplies for electronic systems, where no
input-to-output isolation is required. Their major advantages
include a high level of efficiency, high reliability, low output
ripple, and excellent dynamic response. Models with input
voltages up to 144 V are specially designed for secondary
switched and battery-driven mobile applications. The
converters are suitable for railway applications according to
EN 50155 and EN 50121.
• Extremely wide input voltage range
• Low input-to-output differential voltage
• Very good dynamic properties
• Input undervoltage lockout
• Output voltage adjustment and inhibit function
• Continuously no-load and short-circuit proof
• All boards are coated with a protective lacquer
Two type of housings are available allowing operation up to
71 °C. The PSC Series is designed for wall or chassis
mounting with faston connections, whereas the PSL Series is
designed for insertion into a 19" DIN-rack and exhibits a H11
connector.
Safety-compliant to IEC/EN 60950-1 and UL/CSA
60950-1 2nd Ed.
Various options are available to adapt the converters to
different applications.

Functional Description
complished by varying the duty cycle (on to off ratio) of the
power switch.
The switching regulators are designed using the buck
converter topology. The input is not electrically isolated from
the output. During the on period of the switching transistor,
current is transferred to the output, and energy is stored in the
output choke. During the off period, this energy forces the
current to continue flowing through the output, to the load, and
back through the freewheeling diode. Regulation is ac-
These regulators are ideal for a wide range of applications,
where input to output isolation is not necessary, or where
already provided by an external front end (e.g., a transformer
with rectifier). To optimize customer’s needs, additional options
and accessories are available.

When a switching regulator is located in free, quasi-stationary

after the warm-up phase, measured at the measuring point of
case temperature TC; see Mechanical Data.

Under practical operating conditions, the ambient temperature

output protection is not designed to withstand externally
applied overvoltages.
Output Protection and Short Circuit Behaviour
A voltage suppressor diode, which in worst case conditions
fails into a short circuit (or a thyristor crowbar, option C),
protects the output against an internally generated over-
voltage. Such an overvoltage could occur due to a failure of
either the control circuit or the switching transistor. The
A constant current limitation circuit holds the output current
almost constant, when an overload or a short circuit is applied
to the output. It acts self-protecting and recovers automatically
after removal of the overload or short circuit condition.
Parallel and Series Connection
Vo/Vo nom
05033a
Outputs of equal nominal voltages can be parallel-connected.
However, the use of a single regulator with higher output
power, is always the better solution.
1.0
Io nom
0.8
Io L
In parallel-connected operation, one or several outputs may
operate continuously at their current limit knee-point which will
cause an increase of the heat generation. Consequently, the
max. ambient temperature should be reduced by 10 K.

Outputs can be series-connected with any other regulator. In

the lowest current limitation, but electrically separated source
voltages are needed for each regulator.

The inhibit input allows the switching regulator output to be
disabled via a control signal. In systems with several
converters, this feature can be used, for example, to control
the activation sequence of the converters by a logic signal
(TTL, C-MOS, etc.). An output voltage overshoot will not
occur, when switching on or off.

Standards and Approvals
Safety and Installation Instructions
All switching regulators are class-I equipment and have been
approved according to UL 60950, CSA 60950, and IEC/EN
60950-1 2nd Ed.
Pin Allocation
The pins of PSC models are printed onto the case of the
regulator.
The regulators have been evaluated for:
• Building in
The pin allocation of PSL models is shown in the table below:
• The use in a pollution degree 2 environment
Table 10: H11 connector pin allocation (PSL models)
• Connecting the input to a secondary circuit, which is subject
to a maximum transient rating of 1500 V.

R-input is used for the inhibit function. Consequently, option R
and i exclude each other.
These tests are performed in the factory as routine test in
accordance with EN 50116 and IEC/EN 60950. The electric
strength test should not be repeated by the customer.
Installation Instruction
Railway Application
Installation must strictly follow the national safety regulations
in compliance with the enclosure, mounting, creepage,
clearance, casualty, markings, and segregation requirements
of the end-use application.
The regulators have been developed observing the railway
standards EN 50155 and EN 50121. All boards are coated with
a protective lacquer.
Check for hazardous voltages before connecting.
Connections of PSC models can be made using fast-on or
soldering technique. PSL models should be plugged into a
DIN-rack
The input and the output circuit are not separated, i.e., the
negative path is internally interconnected.
The regulators should be connected to a secondary circuit.
Do not open the regulator !
Ensure that a unit failure (e.g., by an internal short-circuit)
does not result in a hazardous condition.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids must be prevented, since the power supplies
are not hermetically sealed.
Protection Degree
The protection degree is IP 30 (IP 20, if equipped with option
P, D, or D1). It applies only, if the regulator is plugged-in or the
matching female connector is properly attached.

The switching characteristics of the option D output are shown
in fig. Definition of Vt and VH.
Description of Options
-9 Extended Temperature Range
The voltage Vt can be externally adjusted by
a trim
potentiometer. The hysteresis VH of Vt is <2%. Pin D stays low
for a minimum time tlow min, in order to prevent any oscillation. Vt
can be set to a value between Vi min and Vi max. Note that the
JFET becomes conductive, when VD exceeds approx. 7 V.
This option defines an extended temperature range as
specified in table 8.

Option P excludes R function; the R-input (pin 16) should be

L
Input Filter
Fig. 14
Option L is recommended to reduce superimposed inter-
ference voltages and to prevent oscillations, if input lines
exceed the length of approx. 5 m in total. The fundamental
wave (approx. 120 kHz) of the reduced interference voltage
between Vi+ and Gi– has, with an input line inductance of
5 µH, a maximum magnitude of 4 mVAC.

The input impedance of the switching regulator at 120 kHz is
about 3.5 Ω. The harmonics are small in comparison with the
fundamental wave.
With option L, the maximum permissible additionally
superimposed ripple vi of the input voltage (rectifier mode) at
a specified input frequency fi has the following values:

C
Thyristor Crowbar
Table 12: Data of option D
Option C protects the load against power supply malfunction.
It is not designed to sink external currents. A fixed-value
monitoring circuit checks the output voltage Vo. When the
trigger voltage Vo c is reached, the thyristor crowbar triggers
and disables the output. It may be deactivated by removal of
the input voltage. In case of a defect switching transistor, the
internal fuse prevents excessive current.
