Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
Operation under 10% load will not damage the converter; However, they may not meet all specification listed.

APPLICATIONS
PWA_MD-6W & PWB_MD-6W 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:
1) Where the voltage of the input power supply is wide range (voltage range ≤ 4:1); 2) Where isolation is necessary between input and output (Isolation Voltage ≤1500VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

APPLICA TION NOTE
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 PWA_MD-6W & PWB_MD-6W Series have been tested according to the following recommended testing circuit before leaving factory. (See Figure 1).

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). General: Cin: 24V&48V 10μF-47μF
Cout: 10μF/100mA

Input Current
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 startup current of this kind of DC/DC module (See figure 2), General: Ip ≤1.4*Iin-max
No parallel connection or plug and play.
