APPLICATIONS
The F_RN-1W & F_RT-1W series are specially
designed for applications where a group of polar
power supplies are isolated from the input power
supply in a distributed power supply system on a
circuit board.
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
noise
are
not
demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits, and IGBT power
device driving circuits.

APPLICATION NOTE
1) Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, the minimum
output load
could not be less than 10% of the full 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.

2) Recommended testing circuit
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 greatest capacitance of its filter capacitor sees (Table 1).
(Figure2)
3) Output Voltage Regulation and Over-voltage Protection Circuit
The simplest device for output voltage regulation, over-voltage and over-current
protection is a linear voltage regulator with overheat protection that is connected to the
input or output end in series (Figure2).

4) Overload Protection
Under normal operating conditions, the output circuit of these products has no protection
against over load. The simplest method is to connect a self-recovery fuse in series at the
input end or add a circuit breaker to the circuit.
It’s not recommended to connect any external
capacitor in the application field with less than 0.5
watt output.
4) No parallel connection or plug and play
