60 Watt

Isolated, 2:1 Wide Input Range, >Miniature 2.0” x 2.0” x 0.40” Package


DC-DC Converters Feature Miniature Package

Our MWA60/B2A Series of isolated 2:1 wide input range 60-W single output DC-DC converters are housed in a miniature 2.0” x 2.0” x 0.40” package. These devices do not require a minimum load, and they offer high efficiency up to 90 percent, 1600 Vdc isolation voltage and remote ON/OFF control for energy savings. Built-in safeguards include over current, over voltage, short circuit, under voltage and over temperature protections. A six-sided continuous shield minimizes noise leakage. MWA60/B2A Series converters meet IEC/UL/EN60950-1, comply to RoHS and REACH, and they carry the CE Mark.
