DESCRIPTION

The WRE_YD-3W&WRF_YD-3W 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 ≤2:1);

2) Where isolation is necessary between input

and output(Isolation Voltage ≤3000VDC);

3) Where the regulation of the output voltage

and the output ripple noise are demanded.

RECOMMENDED CIRCUIT

APPLICATION NOTE

1) 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.

2) Recommended Circuit

All the WRE_YD-3W & WRF_YD-3W 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).

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 Input

Voltage capacitance of its filter capacitor sees (Table 1).

3) 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)
