PSA/PSR Series
Positive Switching Regulator
The PSA/PSR Series of positive switching regulators are
designed as power supplies for electronic systems when 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 especially designed for secondary-switched and
battery-driven mobile applications. The regulators are suitable
for railway applications according to EN 50155 and EN 50121.
The case design allows for operation up to 71 °C. The PSA/PSR
Series are designed for wall or chassis mounting with faston
connections or with solder pins for insertion into a PCB.
Various options are available to adapt the regulators 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 to 48 VDC
• No input-to-output isolation
• High efficiency up to 95%
• 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
• Boards or chassis mountable

Functional Description
The switching regulators use 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 accomplished by varying the duty cycle (on/off ratio) of the main switch. The regulator starts operating only when the input
voltage exceeds the trigger level of the UVL (undervoltage lockout).

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 TC does not exceed TC max

Output Protection and Short Circuit Behavior
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.
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
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.

Auxiliary Functions
i Inhibit (Remote On/ Off)
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.).
No output voltage overshoot will 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
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). It applies only if the regulator is soldered to the mother board.
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, ≥1 s (for some PSA/PSR models only
with version V103 or higher).
These tests are performed in the factory as routine test in accordance with EN 50514 and EN 60950.
Railway Application
The regulators have been developed observing the railway standards EN 50155 and EN 50121. All boards are coated with a
protective lacquer.

Note: With option R, the ouput voltage Vo is adjusted to 108% of Vo nom, if the regulator doesn’t have option Y in addition.
P
Potentiometer
Option P excludes R function; the R-input (pin 16) should be left open-circuit. The output voltage Vo 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 must be observed.
Note: Option P is not recommended, if several regulators are operated in parallel connection.
Y

Models with rectangular pins 1.0 × 0.5 mm (length 6.5 mm). Such regulators can be fitted to PCB boards (through-plated holes

Accessories
A variety of electrical and mechanical accessories are available including:
• Filters and ring core chockes for ripple and interference reduction; see table 9.
• Tags and isolation pads for easy and safe PCB-mounting
• Adapters for chassis and DIN-rail mounting
Isolation Pads for PCB Mounting
In applications, where PCB mounting converters are placed on top of double sided boards, the use of an isolation pad is
recommended. This fibre foil avoids short circuits and provide excellent protection against possible damage to tracks.
