Features
• RoHS lead-free-solder and lead-solder-exempted
products are available
Description
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.
• 5 year warranty for RoHS compliant products
with an extended temperature range
• Compliant to EN 45545 for (version V104 or later)
• Input voltage up to 144 VDC
• Single output of 3.3 to 48 VDC
• No input-to-output isolation
• High efficiency up to 97%
• Extremely wide input voltage range
• Low input-to-output differential voltage
• Very good dynamic properties
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.
• Input undervoltage lockout
• Output voltage adjustment and inhibit function
• Continuously no-load and short-circuit proof
• All boards are coated with a protective lacquer
Various options are available to adapt the converters to
different applications.
Safety-approved to the latest edition of IEC/EN 60950-1
and UL/CSA60950-1

Positive Switching Regulators
Functional Description
complished by varying the duty cycle (on to off ratio) of the
power switch.The regulator is equipped with a undervoltage
lockout, but no overvoltage shutdown.
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.

Thermal Considerations
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
TA may exceed 71 °C, provided that additional measures (heat

does not exceed its maximum value of 95 °C.

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 output
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 °C.

Outputs can be series-connected with any other regulator. In
series-connection the maximum output current is limited by 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.

Railway Application
Installation Instruction
The regulators have been developed observing the railway
standards EN 50155 and EN 50121. All boards are coated with
a protective lacquer.
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.
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 Liquids
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.

Description of Options
D Input Undervoltage Monitor
Terminal D and Go– are connected to a normally conducting
field effect transistor (JFET). A 0.5 W Zener diode protects
against overvoltages.
-7 Temperature Range
This option defines restricted temperature range as specified
in table 8 (not for new designs).
The switching characteristics of the option D output are shown
in fig. 16.

Note: Option P is not recommended for new designs and not for
several regulators operating in parallel connection.
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
Option P excludes the R function; the R-input (pin 16) should
be left open-circuit. The output voltage Vo can be adjusted in

L
Input Filter
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.

With option L, the maximum permissible additionally super-
imposed ripple vi of the input voltage (rectifier mode) at a

Definition of Vt and VH
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 can be deactivated by removal of
the input voltage. In case of a defect switching transistor, the
internal fuse prevents excessive current.
