Notes:
1. At no load, output voltage accuracy is ±1.5% typical and ±5.0% max.
2. The load on dual output units should not be unbalanced more than ±5 %. Units
operated with unbalanced loads greater than ±5% may not meet all specifications.
3. When measuring output ripple & noise, it is recommended that an external capacitor
(100 µF typ.) be placed from the +VOUT to the -VOUT pins for single output units and
from each output to common for dual output models.
4. Transient recovery is measured to within a 1% error band for a load step change
of 25%.
5. With the addition of the DCFM-0x (or a similar discrete filter), all models will meet EN
55022 class B. A suggested input circuit is shown in the connection diagram on page 3.
Contact the factory for more information.
6. To meet the requirements of EN 61000-4-4 (±2 kV), external components are needed.
The connection diagram on page 3 shows an external input filter that would typically
achieve this. With the addition of the DCFM-0x, EN 61000-4-4 (±4 kV) can be achieved.
Contact the factory for more information.
7. To meet the requirements of EN 61000-4-5 (±2 kV), external components are needed.
This can be done discretely (as shown in the connection diagram on page 3), or with the
addition of the DCFM-0x. Contact the factory for more information.
8. These units should not be operated with a load under 5% of full load. Operation at no-load
will not damage the unit, but they may not meet all specifications.
9. It is recommended that a fuse be used on the input of a power supply for protection. See
the Model Selection table above for the correct rating.

Derating Curve
Remote ON/OFF Control
The MD100x-ERW may be started or shutdown by the control pin input (pin 3). This input is
current controlled. The unit operates when this input is open. When the input is “high” (current
is flowing into the pin), the converter shuts down. The input current to this pin should be kept
between 5 mA to 10 mA. Exceeding 20 mA on this input or connecting it directly to ground
could damage the converter.
The diagram at right gives a suggested input circuit for the control pin. The diode (D1) is an
RB160M-60/1A and CD is is a 47 nF/100V. The resistor R1 is determined by the formula:
R = [(VC-VD-1.0)/IC]-300
Where: VC = voltage to ground from pin 3
VD = the forward conduction voltage drop of D1
IC = the control pin current (5 - 10 mA)

derating of capacitors should be 80% or above.
7. The drawings below show typical board layouts for the EMC/
EMI circuit shown above (one for single output models and
one for dual output units).
8. In many applications simply adding input/output
capacitors will enhance the input surge protection
and reduce output ripple sufficiently. The value of
the input capacitor can range from 10 µF to 100 µF,
depending on the needs of the application. The output
capacitor would typically be 100 µF.
9. The capacitor CS provides additional output filtering.
If used, a value of 10 µF to 20 µF is recommended. This
capacitor is not required for specified operation.

Input noise and surge suppression modules are available for
a number of MPD DC/DC power supplies. An MD100xERW
connection with the DCFM-02 (noise suppression) module
connected to the input is shown in the diagrams below.
The recommended input capacitor (C1) is a 330 µF/50V
for 5, 12, and 24 VDC input models and 330 µF/100V for
48 VDC input units. The output capacitors (C2 & C3) are
100 µF. For pricing or full technical information on these modules (DCFM-01, DCFM-02 and DCFM-03) please contact the factory.
