If the actual output power is very small, please connect a resist or with proper resistance at the output end in parallel to increa se the load, or use our company’s products with a lower rated output power (B_S-W2 & B_D-W2 Series). 2) Overload Protection Under normal operating conditions, the out put circuit of these products has no protec tion against overload. The simplest method is add a circuit breaker to the circuit. 3) Recommended circuit If you want to further decrease the input/output ripple, an capacitor filtering network may be connected to the input and output ends of the DC/DC converter, see (Figure 2). It should also be noted that the capacitance of filter capacito r must be proper. If the capacitance is too big, a startup probl em 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).
