APPLICATION NOTES  
1. Requirement on Output Load  
In order to ensure the product operates efciently and reliably, make sure the specied range of input voltage is not exc
the minimum output load is not less than 10% load. If the actual load is less than the specied minimum load, the ou
increase sharply while its efciency and reliability will reduce greatly. If the actual output power is very small, please a
appropriate resistor as extra loading.  
2. Recommended Circuit  
All VWRBT2 converters have been tested according to the following recommended testing circuit before leang the ftory. This  
series should be tested under load, never under no load (Figure 1).

However, the capacitance of the output lter capacitor must be proper. If the capacitance is to big, a rtuproblem might arise.  
For every channel of output, provided the safe and reliable operation is ensured, the greatest cpacitance of its lter capacitor sees
