The RT9-RD20D1 and RD9-R20D1 Series are
specially designed for applications where a wide
range input voltage power supplies are isolated
from the input power supply in a distributed
power supply system on a circuit board.
These products apply to:

*Input voltage can’t exceed this value, or will cause the permanent damage.
1) Where the voltage of the input power supply is
wide range(voltage range d2:1);
2) Where isolation is necessary between input
and output (Isolation Voltage d1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

Requirement On Output Load

In order to ensure the product operate efficiently and reliably, in addition to a max load
(namely full load), a minimum load is specified for this kind of DC/DC converter. Make sure the
specified range of input voltage is not exceeded, the minimum output load no less than 10%
load. If the actual load is less than the specified minimum load, the output ripple may increase
sharply while its efficiency and reliability will reduce greatly. If the actual output power is very
small, please add an appropriate resistor as extra loading, or contact our company for other
lower output power products.

Recommended Circuit
All the WRA_LT-2W & WRB_LT-2W Series have been tested according to the following
recommended testing circuit before leaving factory. This series should be tested under load.
(See Figure 1).
Iave
If you want to further decrease the input/output ripple, you can increase capacitance
properly or choose capacitors with low ESR. However, the capacitance of the output filter
capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every
channel of output, provided the safe and reliable operation is ensured, the greatest
capacitance of its filter capacitor sees (Table 1).

When it is used in unregulated power supply, be sure that the fluctuating range of the power
supply and the rippled voltage do not exceed the module standard. Input current of power supply
should afford the flash startup average current of this kind of DC/DC module (Figure 2).

OUTLINE DIMENSIONS & PIN CONNECTIONS
.Recommend to use module with more than 10% load, if not, the ripple of the product may exceeds the specification, but does not affect the
reliability of the product;
. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
. Capacitor MAX load tested at input voltage range and full load.
. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
. In this datasheet, all the test methods of indications are based on corporate standards.
. Only typical models listed, other models may be different, please contact our technical person for more details.
The models listed here are just standard type. If you need a product with special specificaꢀon or you have quesꢀons regarding packing standards
(Tube oder Tape/Reel) as well as applicaꢀon support, please contact our specialists: sales@rsg-electronic.de or +49 69-984047-41/-28
