Notes:
Derating Curve
1. At no load, output voltage accuracy is 1.5ꢀ typical and 5.ꢁꢀ max.
2. The load on dual output units should not be unbalanced more than 5 ꢀ. Units
operated with unbalanced loads greater than 5ꢀ may not meet all specifications.
3. When measuring output ripple & noise, it is recommended that an external capacitor
(1ꢁꢁ 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. The maximum output ripple
specified for model MD324S-05ERW is 65 mV.
4. Transient recovery is measured to within a 1ꢀ error band for a load step change
of 25ꢀ.
5. With the addition of the DCFM-0x (or a similar discrete filter), all models will meet EN
55ꢁ22 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 61ꢁꢁꢁ-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 61ꢁꢁꢁ-4-4 ( 4kV) can be achieved.
Contact the factory for more information.
7. To meet the requirements of EN 61ꢁꢁꢁ-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 5ꢀ 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.
Remote ON/OFF Control
The MD300x-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 1ꢁ mA. Exceeding 2ꢁ 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
RB16ꢁM-6ꢁ/1A and CD is is a 47 nF/1ꢁꢁV. The resistor R1 is determined by the formula:
R = [(VC-VD-1.ꢁ)/IC]-3ꢁꢁ
Where: VC = voltage to ground from pin 3
VD = the forward conduction voltage drop of D1
IC = the control pin current (5 - 1ꢁ mA)

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 1ꢁ µF to 1ꢁꢁ µF,
depending on the needs of the application. The output
capacitor would typically be 1ꢁꢁ µF.
9. The capacitor CS provides additional output filtering.
If used, a value of 1ꢁ µF to 2ꢁ µF is recommended. This
capacitor is not required for specified operation.
1. An external fuse should be used in all power module applications.
The recommended fuse is shown in the model chart on page 2.
2. To protect against a surge,an external MOV is recommended on the
input. A suggested value is given in the table at right.
3. To protect against voltage spikes, it is recommended that a TVS be
used on the input. A suggested value is given in the table at right.
4. ThecapacitorCS isrequiredtomeetallspecificationsonsingleoutput
units.
5. The output filtering capacitor (C4) is a high frequency,low resistance
electrolytic capacitor. Care must be taken in choosing this capacitor
not to exceed the capacitive load specification for the unit. Voltage
derating of capacitors should be 8ꢁꢀ or above.
