APPLICATION NOTES
1. Requirement on Output Load
In order to ensure the product operates efficiently and reliably, make sure the specified 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 specifi ed minimum load, the ou
increase sharply while its effi ciency 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 filter 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 filter capacitor sees
