TPD series products are specifically for circuit board need to produce a set of the distributed power system with the input power Source separation of double isolation applications and design of double power supply. This product is applicable to: 1) the input power supply voltage The scope of 2:1 or less; 2) require isolation between input and output of 1500 VDC or less; 3) between two lines of output requirements From the 1000 VDC or less; 4) the output voltage ripple noise to demand higher stability and output.
