APPLICATIONS

The D_(N)S-1W & D_(N)D-1W Series are

100

specially designed for applications where

group of polar power supplies are isolated from

the input power supply in a distributed power

supply system on a circuit board.

100

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.

Requirement on output load

To ensure this module can operate efficiently and

reliably, a minimum load is specified for this kind of

DC/DC converter in addition to a maximum load

(namely full load). During operation, make sure the

specified range of input voltage is not exceeded,

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 testing and application 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

*Test ripple and noise by “parallel cable” method. See detailed operation instructions at Testing

of Power Converter section, application notes.

Note:

1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load

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

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.
