APPLICATIONS
The D_M-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.
COMMON SPECIFICATIONS
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

APPLICATION NOTE
RECOMMENDED CIRCUIT
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.
Recommended circuit
If you want to further decrease the input/output ripple, an “LC” filtering network may be
(Figure 1)

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).
Overload Protection
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.
No parallel connection or plug and play
