These productsapply to: 1) Where the voltage of the input power supply is wide range (Voltage range≤2:1); 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.

Case material ＆EFFICIENCY CURVE DERATING DERATING＆ RECOMMENDED CIRCUIT Output Graph In order to abtain better performance for the DC/DC models.it’s recommended that use input and output filters as Fig.1 shown. 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 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.
