Overload Protection  
OUTPUT SPECIFICATIONS  
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  
input end or add a circuit breaker to the circuit.

If you want to further decrease the input/output  
ripple, an LCfiltering network may be  
connected to the input and output ends of the  
DC/DC converter, see (Figure 1).

TYPICAL CHARACTERISTICS  
It should also be noted that the inductance and  
the frequency of the LCfiltering network should  
be staggered with the DC/DC frequency to avoid  
mutual interference. 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  
recommended capacitance of its filter capacitor  
sees (Table 1).

Requirement on output load  
GND  
To ensure this module can operate efficiently and reliably, During operation, the minimum  
output load is not less than 10% of the full load, and that this product should never be  
operated under no load! If the actual output power is very small, please connect a resistor  
with proper resistance at the output end in parallel to increase the load, or use our companys  
products with a lower rated output power (A_S -W2/B_LS-W2 series).
