Description
The M Series of DC-DC and AC-DC converters represents a
broad and flexible range of power supplies for use in advanced
industrial electronic systems. Features include high efficiency,
reliability, low output voltage noise and excellent dynamic
response to load/line changes due to individual regulation of
each output.
The converter inputs are protected against surges and
transients occuring at the source lines. An input over- and
undervoltage lockout circuit disables the outputs, if the input
voltage is outside the specified range. An inrush current
limitation prevents circuit breakers and fuses from tripping at
switch-on.
All outputs are open- and short-circuit proof, and are protected
against overvoltages by means of built-in suppressor diodes.
The outputs can be inhibited by a logic signal applied to the
connector (pin 2). If the inhibit function is not used, pin 2 should
be connected to pin 23 to enable the outputs.
LED indicators display the status of the converter and allow
visual monitoring of the system at any time.
Table of Contents
Full input to output, input to case, output to case, and output to
output isolation is provided. The converters are designed and
built according to the international safety standard
IEC/EN 60950-1 and UL/CSA 60950-1, and they have been
approved by the safety agencies TÜV and UL.
The case design allows operation at nominal load up to 71 °C
in a free-air ambient temperature. If forced cooling is provided,
the ambient temperature may exceed 71 °C but the case
temperature should remain below 95 °C under all conditions.
A temperature sensor generates an inhibit signal, which
disables the outputs, when the case temperature TC exceeds
the limit. The outputs automatically recover, when the
temperature drops below the limit.
Various options are available to adapt the converters to
individual applications.
The converters may either be plugged into a 19" rack system
according to IEC 60927-3 or be mounted onto a chassis or a
plate.

Functional Description
The input voltage is fed via an input fuse, an input filter, a
rectifier, and an inrush current limiter to the input capacitor.
This capacitor sources a single-transistor forward converter.
Each output is powered by a separate secondary winding of
the main transformer. The resultant voltages are rectified and
their ripples smoothed by a power choke and an output filter.
The main control circuit senses the main output voltage Vo1
and generates, with respect to the maximum admissible output
currents, the control signal for the primary switching transistor.
This signal is transferred to the primary side by a coupling
transformer.
The auxiliary output voltages Vo2 and Vo3 are individually
regulated by means of secondary switching transistors. Each
auxiliary output's current is sensed using a current transformer.
If one of the outputs is driven into current limit, the other
outputs will reduce their output voltages as well, because all
output currents are controlled by the same main control circuit.

Input Fuse
Input Under-/Overvoltage Lockout
A fuse holder containing a slow-blow type fuse (size: 5 × 20
mm) is mounted in the back plate of the converter. The fuse
protects the converter against severe defects. It may not fully
protect it at input voltages exceeding 200 VDC. In applications,
where the converters operate at DC source voltages above
200 VDC, an external fuse or a circuit breaker at system level
should be installed.
If the input voltage remains below 0.8 Vi min or exceeds approx.
1.1 Vi max, an internally generated inhibit signal disables the
output(s). When checking this function the absolute maximum
input voltage rating Vi abs must be carefully considered (see
table Input data).
The fuse and a VDR form together with the input filter an
effective protection against high input transients.
Note: For applications, where the fuse should not be accessible;
see Option F.

Note: When Vi is between Vi min and the undervoltage lockout
level, the output voltage may be below the value defined in table
Output data.
Reverse Polarity
Reverse polarity at the input of AM, BM, CM, DM, and FM
models will cause the fuse to blow. In EM and LM models a
series diode will protect the converter. A series diode is not
incorporated in AM, BM, CM, DM and FM types to avoid
unwanted power losses.
Inrush Current
The CM, DM, EM, and LM (excluding FM) models incorporate
an NTC resistor in the input line, which (during the initial
switch-on cycle) limits the peak inrush current in order to
prevent the connectors and switching devices from damage.
Subsequent switch-on cycles within a short interval will cause
an increase of the peak inrush current due to the warming-up
of the NTC resistor. Refer to Option E.

Output Characteristic and Protection
Each output is protected by a suppressor diode, which under
worst case conditions may become a short circuit. The
suppressor diodes are not designed to withstand externally
applied overvoltages. Overload at any of the outputs will cause
a shutdown of all outputs. A red LED indicates the overload
condition of the respective output.

Caution: The installer must ensure that under all operating
conditions TC remains within the limits stated in the table
Temperature specifications.
Notes: Sufficient forced cooling or an additional heat sink allow TA
to pass over 71 °C, if TC max is not exceeded.
For -7 or -9 models at an ambient temperature TA of 85 °C with
only convection cooling, the maximum permissible current for
each output is approx. 50% of its nominal value; see figure 6.

is therefore, contrary to TC max, an indicative value only.
A temperature sensor generates an internal inhibit signal
disabling the outputs, when the case temperature exceeds
TC max. The outputs automatically recover, when the
temperature drops below this limit.

Main outputs of equal nominal voltage can be connected in
parallel. It is important to assure that the main output of a
multiple-output converter is forced to supply a minimum
current of 0.1 A to enable correct operation of its own auxiliary
outputs.
In parallel operation, one or more of the main outputs may
operate continuously in current limitation, causing an increase
of the case temperature TC. Consequently, a reduction of the
max. ambient temperature by 10 K is recommended.

Dynamic load regulation Vo d versus load change.
Thermal Considerations and Protection
If a converter is located in free, quasi-stationary air (convection
cooling) at the indicated maximum ambient temperature TA max
(see table Temperature specifications) and is operated at its
nominal input voltage and output power, the temperature
measured at the measuring point of case temperature TC (see
Mechanical Data) will approach the indicated value TC max after
the warm-up phase. However, the relationship between TA and
TC depends heavily on the conditions of operation and
integration into a system. The thermal conditions are
influenced by input voltage, output current, airflow, and
BCD20018 Rev AB
Parallel and Series Connection
Main or auxiliary outputs can be connected in series with any
other output of the same or another converter. In series
connection, the maximum output current is limited by the
lowest current limit. Output ripple and regulation values are
added. Connection wiring should be kept as short as possible.
If output terminals are connected together in order to establish
multi-voltage configurations, e.g., +5.1 V, ±12 V etc., the
common-ground connecting point should be as close as
possible to the connectors of the converter in order to avoid
excessive output ripple voltages.
Note: Auxiliary outputs should never be connected in parallel!

Output Current Allocation for Special Models
Output currents differing from those given for standard models
(see Model Selection) can be provided on request. A maximum
output power of 50 W should be considered, if an ambient
temperature range of – 40 to 71 °C is required. The maximum
permissible output currents are indicated in the table below. If
the output voltages are different from standard values, the
relevant output currents have to be adapted accordingly.
With reduced maximum ambient temperature or with forced
cooling, the total output power may exceed 50 W. Customized
configurations always need to be checked by a feasibility study
first. Please ask Power-One for more information.

Hold-up Time and Output Response
When the input voltage is switched off, the output voltage will
remain high for a certain hold-up time t h (see fig. 7) before the
output voltage falls below 0.95 Vo nom. To achieve the hold-up
times indicated in fig. 8, AM, BM, CM, DM, and FM models
require an external series diode in the input line. This is
necessary to prevent the discharge of the input capacitor
through the source impedance or other circuits connected to
the same source. EM and LM models have a built-in series
diode. In AM, BM, CM, DM, and FM models, no series diode is
built-in, since it would generate additional power losses inside
the converter.
The behavior of the outputs is similar with either the input
voltage applied or the inhibit switched low.
No output voltage overshoot occurs, when the converter is
turned on or off.

Auxiliary Functions
Inhibit
Iinh [mA]
The outputs of the converters may be enabled or disabled by
means of a logic signal (TTL, CMOS, etc.) applied between the
inhibit input i and the negative pin of output 1 (Vo1–). In
systems with several converters, this feature can be used, for
example, to control the activation sequence of the converters.
If the inhibit function is not required, connect the inhibit pin 2 to
pin 23 to enable the outputs (active low logic, fail safe). The
response times are specified in table 6.

R-Control for Output Voltage Adjustment
As a standard feature, single-output models without option P
offer an adjustable output voltage identified by letter R in the
type designation.
Note: With open R input, Vo = Vo nom.
The output voltage Vo can either be adjusted by an external
voltage (Vext) or by an external resistor (Rext1 or Rext2). The
adjustment range is approximative 0 – 110% of Vo nom. For
output voltages Vo > Vo nom, the minimum input voltage Vi min
specified in Electrical Input Data increases proportionally to
Vo/Vo nom.
a) Adjustment by means of an external resistor Rext.
Depending upon the value of the required output voltage,
the resistor shall be connected:
either: Between the R and G pin to achieve an output
voltage adjustment range of Vo ≈ 0 to 100 % of Vo nom.

Rext1 ≈ 4 kΩ • –––––––––
