APPLICATIONS

Storage humidity range

The D-XNM 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:

Short circuit protection*

Cooling

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.

APPLICATION NOTE

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

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 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).

It's not recommended to connect any external capacitor in the

application field with less than 0.5 watt output.

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
