Sec 1223 Power Supply Schematic

Or 240 vac, 50 hz to regulated 13.8 vdc based on pulse width modulation ( pwm ). Got the schematic and made repairs, same issue on both units: Apparently, the sec1223 has a bad reputation for being noisy and various users added an rfi filter on the output. I built it using a 7 metre sotabeams tactical (very strong!) telescoping qrp pole with the segments epoxied together.

Web Maybe It's Failed.

Web my latest project is a new rybakov aerial. Web [#2] a bit of theory, a smps takes the 120 vac input rectifies, filters it and uses the output to run an oscillator. The oscillator is designed to run faster, on loading by.
