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. Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. he simest method s to
connect a self-recovery fuse in series at the end or add a circuit breaker to the circuit.

3. Recommended Circuit
All VWRBS1 converters have been tested according to the following recommended testing rcuit befre leavinthe factory. This
series should be tested under load, never under no load (Figure 1).

However, the capacitance of the output filter capacitor must be proper. Ithe capacitance is too big, a startup problem might arise.
For every channel of output, provided the safe and reliable peration is enred, the greatest capacitance of its filter capacitor sees

When open or high impedce, the converer work well; When this pin is ‘high’; the converter shutdown; It should be note that the
input current shoulbetwe5~10 mA, ceeding the maximum 20 mA will cause permanence damage to the converter.

5. Input Crent
While using unstable power source, please ensure the output voltage and ripple voltage do not excced indexes of the converter. The
