These products apply to: 1) Where the voltage of the input power supply is wide range (voltage range2:1); 2) Where isolation is necessary between input and output(Isolation Voltage3000VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

Note:The load shouldn't be less than 10%,otherwise ripple will increase dramatically. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.

This series should be tested under load. Never be tested under no load (see Figure 1). Dual Output Vin C in +Vout DC DC 0V -Vout GND Single Output Vin Cin +Vout DC DC 0V GND TYPICAL CHARECTERISTICS Temperature Derating Graph (Figure 1) If you want to further decrease the input/output ripple, you can increase 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 Safe Operating Area 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).

Input current of power supply should afford the startup current of this kind of DC/DC module.

Make sure the specified range of input voltage is not exceeded, the minimum output load no less than 10% load. If the actual load is less than the specified minimum load, the output ripple may increase sharply while its efficiency and reliability will reduce greatly. If the actual output power is very small, please add an appropriate resistor as extra loading, or contact our company for other lower output power products. No parallel connection or plug and play.
