APPLICATIONS
The MSA_(M)D-3W &MSB_(M)D-3W Series are specially designed for applications where a wide range input voltage 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 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 dem anded.

Input Voltage Range
(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 o.
