FAK 12-4.2K (KEPCO)

The Kepco FAK 50 Watt Series low profile high frequency switching power supplies employ forward conversion and operate at 80% efficiency with either a-c or d-c input. A thermistor soft-start circuit limits start-up surge. Surface mount technology permits efficient compact topology for minimum mounting space. Four models may be selected for outputs of 5, 12, 15 or 24V. A green “POWER OK” light is provided. A steel cover (Model CA 23) is available as an option. Output voltage may be adjusted with a trimmer accessible near the input-output barrier strip. When the input is cut off, the output is maintained for 20–30 milliseconds (30 milliseconds typical). EMI filtering meets FCC Class B rating.
