APPLICATIONS
The MSA_(M)D-3W & MSB_(M)D-3W series are designed
for applications where the output power is directly introduced
into the power control circuit board After the AC / DC converter
filter circuit from a distributed power system. For these DC-DC
converters, You can reduce the design point of failure and save
the development of micro power supply‘s manpower, material
and time costs, also better ensure product quality stability,
protect safety and reliability of the end of products.
These products apply to where:
1) Input voltage variation range≤ 2:1;
2) 1.5KVDC input and output isolation;
3) Regulated and low ripple noise are required.

DESIGN CONSIDERATIONS
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) Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is add a circuit
breaker to the circuit.
3) Recommended circuit
All the MSA_(M)D-3W & MSB_(M)D-3W Series have been tested according to the following recommended testing circuit before leaving
factory(Figure 3).
If you want to further decrease the input/output ripple, you can increase a capacitance properly or choose capacitors with low ESR. 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 must less than the Max. Capacitive Load. Generally:
If you want to use the products in high EMI, please choose our metal packaged products (MSA_MD-3W & MSB_MD- 3W).
