TYPICAL CHARACTERISTICS It should also be noted that the inductance and the frequency of the "LC"filtering 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 greatest capacitance of its filter capacitor sees (Table 1).

Overload Protection Under normal operating conditions, the output circuit of these products has no protection against over-current and short-circuits.The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. OUTLINE DIMENSIONS & PIN CONNECTIONS SIZE Graph 2W SIP IF IF--XSXS-2 Input Over-voltage Protection Circuit The simplest device for input over-voltage protection is a linear voltage regulator with overheat protection that is connected to the input end in series(Figure 2).
