APPLICATIONS
The PWA_(M)D-1W5&PWB_(M)D-1W5 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 4:1); 2) Where isolation is necessary between input and output (Isolation Voltage1500VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

* Input voltage over it may cause permanent damage to the device. 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.

APPLICATION NOTE
Input Voltage (V)
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. No parallel connection or plug and play.
