1) Where the voltage of the input power supply

is wide range (voltage range ≤2:1);

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.

Output Voltage

*Input voltage can’t exceed this value, or will cause the permanent damage.

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.

Recommended Circuit

COMMON SPECIFICATIONS

All the WRA_YMD-6W & WRB_YMD-6W Series

have been tested according to the following

recommended testing circuit before leaving

factory. This series should be tested under load.

Never be tested under no load (see Figure 1).

Note:

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:

1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load unless

otherwise specified.

2. See below recommended circuits for more details.

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. (Figure 2).

APPLICATION 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.

No parallel connection or plug and play.
