APPLICATIONS

The D_(N)S-1W & D_(N)D-1W Series are specially designed for applications where a group of polar power supplies are isolated from the input power sup ply 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) Wh ere 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.

Dur ing 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 con nect 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 converter, see (Figure 1). Vin GND +Vo1 0V1 DCCin L DC Cout +Vo2 0V2 L Cout L (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 regula tor with overheat protection that is connected to the input or output end in series (Figure 2). Vin GND Vin GND REG Vo1 0V1 +Vout DC DC DCDC Vo2 0V2 +Vout REG REG (Figure 2) Overload Protection Under normal operating conditions, the output circuit of these products has no protection again st 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.
