1) Where the voltage of the input power
supply is fixed (voltage variation ≤±5%);
2) Where isolation is necessary between
input
and
output
(isolation
voltage
≤1000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

*Supply voltage must be discontinued at the end of short circuit duration.
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
simplest
method is to connect a self-recovery fuse in series
at the input end or add a circuit breaker to the
circuit.
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

When the environment temperature is higher
than 71°C, the product output power should be
less then 60% of the rated power.
No parallel connection or plug and play.
APPLICATION NOTE
Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, 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.
