APPLICATIONS
The B_(X)T-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
≤1000VDC);
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.

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.
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).

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).

Overload Protection
Under normal operating conditions, the output
circuit of these products has no protection against
over-current and short-circuits. The simplest
method is to connect a self-recovery fuse in series
at the input end or add a circuit breaker to the
circuit.
No parallel connection or plug and play.
