These products apply to:

1) Where the voltage of the input power supply is
fixed (voltage variation ≤±10%);
2) Where isolation is necessary between input
and output (isolation voltage ≤3000VDC);
3) Where the regulation of the output voltage and
the output ripple and noise are not demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits and IGBT power
device driven circuits, etc.

COMMON SPECIFICATION
If you want to further decrease the
input/output ripple, an “LC” filtering network may
be connected to the input and output ends of the
DC/DC converter, see (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 recommended capacitance of its
filter capacitor sees (Table 1).

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.
APPLICATION NOTE
Requirement On Output Load
To ensure this module can operate efficiently and reliably, a minimum load is specified for
this kind of DC/DC converter in addition to a maximum load (namely full load). During
operation, make sure the specified range of input voltage is not exceeded, the minimum
output load is not less than 10% of the full load, and that this product should never be
operated under no load! If the actual output power is very small, please connect a resistor
with proper resistance at the output end in parallel to increase the load, or use our company’s
products with a lower rated output power.
No parallel connection or plug and play.
