APPLICATION NOTES
Requirement on Output Load
In order to ensure the product operates efficiently and reliably, make sure the specified range of input voltage is not exceeded and
the minimum output load is not less than 10% load. If the actual load is less than the specifi ed minimum load, the output ripple may
increase sharply while its effi ciency and reliability will reduce greatly. If the actual output power is very small, please add an
appropriate resistor as extra loading.
2.
Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to
connect a self-recovery fuse in series at the end or add a circuit breaker to the circuit.

Recommended Circuit
All VWRBS1 converters have been tested according to the following recommended testing circuit before leaving the 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. If the capacitance is too big, a startup problem might arise.
For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees

When open or high impedance, the converter work well; When this pin is ‘high’; the converter shutdown; It should be note that the
input current should between 5~10 mA, exceeding the maximum 20 mA will cause permanence damage to the converter.
