The A_S-1W & B_LS-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.

Overload Protection
OUTPUT SPECIFICATIONS
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.

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).

TYPICAL CHARACTERISTICS
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).

Requirement on output load
GND
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 (A_S -W2/B_LS-W2 series).
