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
input end or add a circuit breaker to the circuit.
(Figure 1)
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
