These products apply to: 1) W here the voltage of the input power supply is fixed (voltage variation ≤ ±10%); 2) W here isolation is necessary between input and output (isolation voltage ≤1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits. 12 10.8-13.2 15 13.5-16.5 24 21.6-26.4 MODEL SELECTION A0505D-1W Rated Power Package Style Output Voltage Input Voltage Product Series UL UL UL UL UL CE UL CE UL CE UL CE Note: The A_D-W 25/B_LD-W25 series also are available in our company.
