APPLICATIONS
The WRB_T-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≤1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

If you want to further decrease the input/output
ripple, you can increase capacitance properly or
choose capacitors with low ESR. However, the
capacitance should not be too high(Table 1)

APPLICATION NOTE
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%
full load, If the actual load is less than the specified minimum load, the output ripple may
increase sharply. 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.
