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 demanded. 24 18-36 40 48 36-72 80 MODEL SELECTION WRB0512SP-3W Rated Power Package Style O utput Voltage Input Voltage Product Series *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.
