Description
• Input voltage up to 144 VDC
The PSS/PSK Series of positive switching regulators is
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.
• 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
• Input undervoltage lockout
Two type of housings are available allowing operation up to
71 °C. They are designed for insertion into a 19" DIN-rack or
for chassis mounting. Replacing the heat sink by an optional
cooling plate, allows chassis or wall mounting on top of a metal
surface, acting as heat sink.
• Active current sharing for parallel operation
• Output voltage adjustment, inhibit, and sense lines
• Continuously no-load and short-circuit proof
• All boards are coated with a protective lacquer
Various options are available to adapt the converter to different
applications. Connector type: H15 or H15S4, depending on
output current.

Functional Description
back through the freewheeling diode. Regulation is
accomplished by varying on/off duty cycle.
The switching regulators are using the buck converter
topology. The input is not electrically isolated from the output.
During the on period of the switching FET, 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 chocke to the load and
These regulators are ideal for applications, where an input to
output isolation is not necessary or where it is already provided
by an external front end, e.g., a transformer with rectifier. To
optimize customer’s needs, various options and accessories
are available.

characteristic of a switched mode regulator. The input fuse
protects against severe defects.
Input Filter and Fuse
An input filter and a fuse are incorporated in all converters as
standard. The filter reduces emitted electrical noise and
prevents oscillations caused by the negative input impedance
The maximum permissible additionally superimposed ripple vi
of the input voltage (rectifier mode) at a specified input
frequency fi has the following values:
Table 3: Input fuses
vi max = 10 Vpp at 100 Hz, or Vpp = 1000 Hz/fi • 1 V
The input fuses are specified in the table 3.

Inrush Current
Depending on the input source and the input impedance, the
inrush current into the converter may reach a very high peak
value during the switch-on sequence. It also determine the
rating of input devices such as switches, relays, fuses, etc. To
protect these input devices by limiting the inrush current, we
recommend the choice of the active inrush current limitation
circuit, option E.

Dynamic load regulation.
Output Protection
Outputs can be series-connected with any other regulator,
provided that the regulators are powered by electrically
isolated source voltages. In series connection the maximum
output current is limited by the lowest current limitation.
A voltage suppressor diode, which in worst case conditions
fails into a short-circuit, protects the output against an
internally generated overvoltage. Such an overvoltage could
occur due to a failure of either the control circuit or the
switching transistor. The output protection is not designed to
withstand externally applied overvoltages.
Current Limitation
A constant current limitation circuit holds the output current Io
almost constant in the area of 100 to 120% of Io nom, when an
overload or a short-circuit is applied to the output. It acts self-
protecting and recovers – in contrary to the fold back method –
automatically after removal of the overload or short-circuit
condition.

sink, forced cooling, etc.) are taken to ensure that the case
temperature TC does not exceed its maximum value.
Thermal Considerations and Protection
When a switching regulator is located in free, quasi-stationary
air (convection cooling) at a temperature TA max and is operated
at its nominal output current Io nom, the case temperature TC
can rise over TC max after the warm-up phase. TC is measured
at the measuring point of case temperature; see Mechanical
Data.
The regulater is protected by an internal temperature sensor,
which inhibits the output above TC max
automatically recovers, when the temperature drops below
TC max

This feature enables compensation of the voltage drop across

To ensure correct operation, both sense lines must be

The output voltage Vo can either be adjusted with an external

Current Sharing
Test Sockets
For parallel operation of several regulators, interconnect all T-
pins to ensure that the output currents are evenly distributed.
This feature improves transient load performance and
increases system reliability. All paralleled regulators should be
supplied by equal input voltage (Vi). The output lines should
exhibit equal length and cross section to provide equal voltage
drop.
Test sockets (pin ∅ = 2 mm) for measuring the output voltage
Vo at the sense lines, are located at the front side of the
regulator. The test sockets are protected by a series resistor.

Installation Instruction
Safety and Installation Instructions
Installation of the regulators 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.
Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15 or H15S4
connector. Pin 24 (protective earth) is a leading pin, which
provides electrical contact first. The regulators should only be
wired via the female connector H15 (according to DIN 41612)
to ensure requested safety!
The input and the output circuit are not separated. The
negative path is internally interconnected.
The regulators should be connected to a secondary circuit.
Make sure that a regulator failure (e.g. by an internal short-
circuit) does not result in a hazardous condition.

Option P excludes R function; the R-input (pin 16) should be
left open-circuit. The output voltage Vo can be adjusted in the
Fig. 13
range 90 - 110% of Vo nom
.
Option E: Inrush current versus time. Rs is the startup resistor
(Rs = 1 Ω for models with Vi max ≤ 80 V, Rs = 15 Ω for models
with Vi max > 80 V)
However, the minimum differential voltage Vi max between input
and output as specified in Electrical Input Data should be
maintained.
E
Inrush Current Limitation
Depending on the application, further decentralized
overvoltage protection elements may have to be used
additionally.
Note: This option requires an increased minimum input voltage
Vi max of up to 1 V, dependent upon input range.
In regulators without option E, after application of the input
supply the inrush current is limited by parasitic components of
the voltage source and the regulator input only. The regulator
input exhibits a very low impedance, and when driven from a
low impedance source, for example a battery, the inrush
current can peak at several orders of magnitude above the
continuous input current.
A fixed-value monitoring circuit checks the output voltage Vo,
and when the trigger voltage Vo c is reached, the thyristor
crowbar triggers and disables the output.
An external connection C (crowbar trigger control) is provided.
When crowbar option is used with two or more power supplies
in parallel connection, all crowbar trigger terminals (C) should
be interconnected. This ensures all crowbar circuits triggering
simultaneously, in order to disable all outputs at once. The
crowbar trigger voltage is maintained between Vo+ and Go–.
To prevent false triggering, the user should ensure that Vo
Option E dramatically reduces this peak current and is
recommended for any application to protect series elements
such as fuses, switches, or circuit brakers. The startup circuit is
bypassed during normal operation.
(between Vo+ and Go–) deos not exceed Vo c
.
C
Thyristor Crowbar
G
RoHS Compliance
Note: The crowbar can be reset by removal of the input voltage
only. The inhibit signal cannot deactivate the thyristor.
Models with G are RoHS-compliant for all six substances.
Option C protects the load against power supply malfunction. It
is not designed to sink external currents.
As a central overvoltage protection device, the crowbar is
usually connected to the external load via distributed
inductance of the lines. For this reason, the overvoltage at the
load can temporarily exceed the trigger voltage Vo c
.

EC Declaration of Conformity
We
Power-One AG
Ackerstrasse 56 CH-8610 Uster
declare under our sole responsibility that all PSx Series switching regulators carrying the
CE-mark are in conformity with the provisions of the Low Voltage Directive (LVD) 2006/95/
EC of the European Communities..
Conformity with the directive is presumed by conformity wih the following harmonized
standards:
• EN 61204: 1995 (= IEC 61204: 1993, modified)
Low-voltage power supply devices, DC output - Perfomance characteristics
and safety requirements
• EN 60950: 1992 + A1: 1993 + A2 (= IEC 950 second edition 1991 + A1: 1992 +
A2: 1993) - Safety of information technology equipment
The installation instructions given in the corresponding data sheet describe correct installation
leading to the presumption of conformity of the end product with the LVD. All PSx Series
Switching Regulators are components, intended exclusively for inclusion within other
