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

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.
Note:
1. All specifications measured at Ta=25°C, humidity<75%,
nominal input voltage and rated output load unless
otherwise specified.
2. Only typical models listed, specifications of custom
product may be different. Please contact our service
people directly for certain conditions.
3. Operation under minimum load will not damage the
converter; However, they may not meet all specification
listed.
