The PT-45C is a 43.5W Triple Output Switching Power Supply. PT-45C operates from 90 to 264VAC. Voltage output is for channel 1 is 5V at rated current 3A and for channel 2 is 15V at rated current 1.6A and -15V at .3A for channel 3 . Thanks to the high efficiency up to 75%, it is able of operating from -10 to +60 ℃ case temperature under free air convection. The PT-45C uses different protection techniques such as short circuit/over load /over voltage/ over temperature with low leakage current <.5mA. The PT-45C has a 2 years factory warranty.
