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. It’s not recommended to connect any

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.
No parallel connection or plug and play.
