COMMON SPECIFICATIONS
Parameter
APPLICATIONS
The WRB_YD-30W 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 circuitboard.
These productsapply 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.

Output Graph
In order to abtain better performance for the DC/DC
models.it’s recommended that use input and output
filters as Fig.1 shown.
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
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.
