Functioning
The input terminals can be connected nap. alternating or constant (pulse or filtered). Due to the high frequency converter, some very sensitive radio or microprocessor can operate correctly. It is recommended that you install an additional filter (consisting of a choke current compensated for inductance 2× 5÷15mH and a capacitor C= 0.33÷1μF) between power supply and receiver. With increasing load above Imax will stabilize the AC current, output voltage will decrease. When the power supply output terminals operates at a frequency around 1.5 kHz, which is manifested as a clear noise.
