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. 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. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits.

See detailed operation instructions at Testing of Power Converter section, application notes. Operating Temp.(C) o 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 y ou 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 saf e 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 protec tion 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 oper ating 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.
