Parallel or serial operation of several converters with equal output voltage is possible, however it is not advantageous to connect
converters in parallel without measures to provide reasonable current sharing. Choose suitable single-output models, if available.
Note: Unused tracking outputs should be connected parallel to the respective regulated output.

Outputs of single-output powertrains are also protected by a suppressor diode.
The temperature of the heat sink is monitored and causes the converter to disable the outputs. After the temperature dropped,
the converter automatically resumes.

small input capacitance Ci resulting in low inrush current of short duration. As a result, in a power-bus system the units can be hot
plugged-in or disconnected causing negligible disturbances at the input side.
Input Stability with Long Supply Lines
If a converter is connected to the power source by long supply lines exhibiting a considerable inductance Lext, an additional external
capacitor Cext connected across the input pins im proves the stability and prevents oscillations.
Actually, a P Series converter with its load acts as negative resistor ri, because the input current Ii rises, when the input voltage Vi
decreases. It tends to oscillate with a resonant fre quency determined by the line inductance Lex t and the input capacitance Ci + Cext,
damped by the resistor Rext. The whole system is not linear at all and eludes a simple calculation. One basic condition is given by
the formula:
Lext
Po max dVi
Ci + Cext > _________ ( ri = _____ )
RextVi min² dIi

stable operating conditions. Worst case conditions are a lowest Vi and at highest output power Po.
Low inductance Lext of the supply lines and an additional capacitor Cext are helpful. Recommended values for Cext are given in table 4,
which should allow for stable operation up to an input inductance of 2 mH. Ci fi

Notes:
If a tracking output is not used, connect it in parallel to the respective regulated main output.
Connection of several outputs in parallel should include measures to approximate all output currents. 3.3 and 5 V outputs with option T have
current-share pins (T), which must be interconnected. For other outputs, the load lines should exhibit similar resistance. Parallel connection
of regulated outputs without such precautions is not recommended.
The maximum output current of series-connected outputs is limited by the output with the lowest current limit.
Rated output voltages above 48 V (SELV = Safety Extra Low Voltage) require additional safety measures in order to comply with international
safety standards.

5.1 V and load 2 with 12 V.
The converters are separated with ORing diodes. If one converter fails, the remaining one still delivers the power to the loads. If
more power is needed, the system may be extended to more parallel converters (n+1 redundancy).
Current sharing of the 5.1 V outputs is ensured by the interconnected T pins, whereas the sense lines are connected after the
ORing diodes to maintain the correct output voltage.
For the 12 V outputs, no current-share feature (option T) is available. As a result, 2 little diodes Ds (loaded by little resistors Rs)
simulate the voltage drop of the ORing diodes. Reasonable current sharing is provided by load lines of equal length and section.

loop protects the tracking outputs against overvoltage by reducing the voltage of the respective regulated main output.
Because the P Series converters exhibit main transformers and main chokes in planar technology, the tracking outputs follow the

Output Current Limitation
All outputs are continuously protected against open-circuit (no load) and short-circuit by an electronic current limitation.
Single- and double-output powertrains have a rectangular current limitation characteristic. In double output power-trains only
the total current is limited allowing free choice of load distribution between the two outputs of each power train up to a total
Io1 + Io4 = Io max or Io2 + Io3 = Io max.
Thermal Considerations and Protection
If a converter is mounted upright in free air, allowing unrestricted convection cooling, and is operated at its nominal input voltage
and output power at TA max (see table Temperature specifications), the temperature measured at the measurement point on the
case TC (see Mechanical Data) will approach TC max after an initial warm-up phase. However the relationship between TA and TC

automatically resumes, when the temperature drops below this limit. An additional temperature sensor on each power train
reduces the output current limit of that power train, when the temperature exceeds a safe level.
Output Power at Reduced Temperature
Operating the converters with an output current between Io nom and Io max requires a reduction of the ambient tem perature or forced
air cooling, in order to keep TCfiTC max is exceeded, the thermal protection is activated and disables
the outputs.
Note: Forced cooling or an additional heat sink can improve the reliability or allow TA to go beyond TA max, provided that TC max is not exceeded.
In rack systems without proper thermal management the converters should not be packed too closely together! In such cases the use of a 5
or 6 TE front panel is recommended.

Auxiliary Functions
Primary Inhibit (Remote On / Off)
The inhibit input enables (logic low, pull down) or disables (logic high, pull up or open-circuit) the output, if a logic signal (TTL,
CMOS) is applied. In systems consisting of several converters, this feature may be used to control the activation sequence by logic
signals or to enable the power source to start up, before full load is applied.

Output Voltage Adjust of Vo1 and Vo4
Note: With open R-input, Vo = Vo nom.
The converters allow for adjustment of the voltage of power train 1. Powertrain 2 can not be adjusted (except for single-output
models). The programming is performed either by an external control voltage Vext or an external resistor R1 or R2, connected to the
R-input. Trimming is limited to the values given in the table Electrical Output Data.

Sense Lines
Important: Sense lines should always be connected. Incorrectly connected sense lines may damage the converter. If sense pins are left open-
circuit, the output voltages are not accurate.
This feature enables compensation of voltage drop across the connector contacts and the load lines including ORing diodes in
true redundant systems.

High currents require a large cross-sectional area of the connections to the female contacts. We recommend solder or screw terminal
contacts. Each faston connection exhibits a resistance of typ. 4 m Ω (max. 8 mΩ), which makes it less suitable for high currents.
For single-output models with option K, both output contacts must always be used and connected in parallel to the load with large cross-

Installation Instructions
These converters are components, intended exclusively for inclusion within other equipment by an industrial assembly process or
by a professionally competent person. Installation must strictly follow the national safety regulations in respect of the enclosure,
mounting, creepage distances, clearances, markings and segregation requirements of the end-use application.
Connection to the system shall be made via the female connector H15 or H15S2 (see Accessories). Other installation methods

within its regulation limits. This could occur, because the input voltage is below the minimum level or the load current is too high.
This function is not adjustable.
A galvanically isolated open-collector output generates the “Out OK” signal. The circuit monitors simultaneously that
the input voltage is present and the inhibit signal enables the converter - same logic as LED “In OK”
the output voltages are within their limits - same logic as LED(s) “Out OK”.

Output OK circuit (option D)
Option T: Active Current Sharing
For 3.3 V and 5.1 V outputs only. The current share facility should be used, when several converters are operated in parallel.
Examples could be high reliability n+1 redundant systems or systems providing higher output power.
Using this feature reduces the stress of individual converters and improves the reliability of the system. Interconnection of the
current-sharing T-pins causes the converters to share their output currents evenly.
In redundant systems, the outputs of the converters are decoupled by ORing diodes. Consequently, a failure of one converter will
not lead to a system failure.
Since the voltage on the T-pin is referenced to the sense pin S–, the installer must ensure that the S– pins of all parallel converters
are at the same electrical potential and that there are no voltage drops across the connection lines between these pins.
Double-output converters with outputs connected in series can also be paralleled with current sharing, if pins Vo1– of all converters
