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≤3000VDC); 3) Where the regulation of the Output voltage and the output ripple noise are demanded. NOTE: High power-density, a wide temperature range of -40℃~+71℃and extra features like Remote On-Off function are just some of the characteristics of this versatile compact converter, ideal for highly sophisticated industrial designs where space is at a premium.
