These products apply 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& Vout1 and Vout2(Isolation Voltage1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

Generally, the capacitance is no greater than 47uF 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, If the actual load is less than the specified minimum load, the output ripple may increase sharply. 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.
