PSB Series
Positive Switching Regulator
The PSB Series of 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 144V 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.
The case design allows for operation up to 71 °C. The PSB Series
is designed for wall or chassis mounting with faston connectors.
Various options are available to adapt the converters to different
applications.
Features
• RoHS lead-free-solder and lead-solder-exempted
products are available
• 5 year warranty for RoHS compliant products with an
extended temperature range
• Input voltage up to 144 VDC
• Single output of 5.1 to 48 VDC
• No input-to-output isolation
• High efficiency up to 96%
• Extremely wide input voltage range
• Low input-to-output differential voltage
• Very good dynamic properties

Functional Description
This switching regulator uses 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 keep flowing through the output, to the load, and back through the freewheeling diode. Regulation is
accomplished by varying the duty cycle (on/ratio) of the power switch. The regulator is equipped with a undervoltage lockout, but
no overvoltage shutdown.
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.

Switching regulator with long supply lines.
Parallel and Series Connection
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.
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 series-connection the maximum output current is limited by the lowest
current limitation, but electrically separated source voltages are needed for each regulator.
Thermal Considerations
When a switching regulator is located in free, quasi-stationary air (convection cooling) at a temperature TA = 71 °C and is operated
at Io nom, the case temperature TC will be about 95°C after the warm-up phase, measured at the measuring point of case temperature
TC; see Mechanical Data.
Under practical operating conditions, TA may exceed 71 °C, provided that additional measures (heat sink, fan, etc.) are taken to
ensure that the case temperature TC does not exceed TC max
.
The regulators with Vi max = 144 V withstand 156 V for 2 s in order to comply with railway standards. However, Io max is only
continuously available for Vi ≤ 80 V or for reduced TA and TC; see fig. 4c.

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 protection is not designed to withstand externally applied overvoltages.
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.

Auxiliary Functions
i Inhibit (Remote On/ Off)
The inhibit input allows for disabling the switching regulator by a control signal. In systems with several converters, this feature can be used,
for example, to control the activation sequence of converters by a logic signal. An output voltage overshoot will not occur at switch on.
Note: With open i-pin, the output is enabled.

Safety and Installation Instructions
Installation Instruction
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.
The input and the output circuit are not separated, i.e., the negative path is internally interconnected.
Do not open the regulator !
Ensure that a regulator failure (e.g., by an internal short-circuit) does not result in a hazardous condition.
Cleaning Liquids and Protection Degree
In order to avoid possible damage, any penetration of cleaning fluids must be prevented, since the power supplies are not
hermetically sealed.
The protection degree is IP 30 (IP 20 with option P).
Standards and Approvals
All switching regulators have been approved according to the latest edition of IEC/EN60950-1 and UL/CSA60950-1.
The regulators have been evaluated for:
• Building in
• The use in a pollution degree 2 environment
• Connecting the input to a secondary circuit, which is subject to a maximum transient rating of 1500 V.
The switching regulators are subject to manufacturing surveillance in accordance with the above mentioned standards and with
ISO 9001:2015.
Isolation
Electric strength test voltage between input connected with output against case: 1500 VDC, 10 s (for some PSB models only with
version V103 or higher).
These tests are performed in the factory as routine test in accordance with EN 50514 and IEC/EN 60950. The electric strength
test should not be repeated by the customer.
Railway Application
The regulators have been developed observing the railway standards EN 50155 and EN 50121. All boards are coated with a
protective lacquer.

Description of Options
-9 Extended Temperature Range
This option defines an extended temperature range as specified in table 7.
P
Potentiometer
Note: Option P is not recommended, if several regulators are operated in parallel connection.
Option P excludes R function; the R-input (pin 16) should be left open-circuit. The output voltage Vo is preset to 108 % of Vo nom and
can be adjusted in the range 90 – 108% of Vo nom
.
However, the minimum differential voltage ∆Viomin between input and output specified in Electrical Input Data should be observed.
L
Input Filter
Option L is recommended to reduce superimposed interference 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
frequencyfi has the following values:
vi max = 10 Vpp at 100 Hz or Vpp = 1000 Hz/fi × 1 V
C
Thyristor Crowbar
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 (see table 9) 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.
Type of the fuse:
• Regulators with Io nom = 3 A: 5 A / 250 V, slow, 5 × 20 mm
• Regulators with Io nom > 3 A: 8 A / 250 V, slow, 5 × 20 mm
Note: The crowbar can be reset by removal of the input voltage only. The inhibit signal cannot deactivate the thyristor.
