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 Voltage 1500VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded. 24 18-36 40 48 36-72 80 *Input voltage can't exceed this value, or will cause the permanent damage. 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.

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).

APPLICATION NOTE Requirement on Output Load In order to ensure the product operate efficiently and reliably, in addition to a max load (namely full load), a minimum load is specified for this kind of DC/DC converter. 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.
