APPLICATIONS
The A_S-1WR & B_LS-1WR 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)
2)
3)
Where the voltage of the input power
Where isolation is necessary between
Where the regulation of the output voltage
supply is fixed (voltage variation
≤ ±10%);
input and output (isolation voltage
≤1000VDC);
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 resistance of 10% rated power at the
output end in parallel, or use our company’s products with a lower rated output power

②
Overload Protection
Under normal operating conditions, the output circuit of these products has no
protection against overload. The simplest method is to connect a slow-blow fuse in series
at the input end or add a circuit breaker to the circuit.

③
Recommended testing and application circuit
If you want to further decrease the input ripple or the input inrush current, 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).

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 (Figure 2).

.The recommended external capacitance please use the
ceramic capacitor;
2. For applications where output power is less than 0.5W in
reality, external capacitors are not recommended.

Note:
1. Operation under minimum load will not damage the converter; However, they may not meet all specification listed, and that will reduce the life of
product.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
3. In this datasheet, all the test methods of indications are based on corporate standards.
4. Only typical models listed, other models may be different, please contact our technical person for more details.
