When adjusting the output voltage care should be taken never to exceed the stated output power or output current of the unit. 2. At full load, nominal input, 20 MHz bandwidth oscilloscope, tip & barrel method, output terminated with 10 F electrolytic and 0.1 F ceramic capacitors. Under light load conditions (<15%) the measurement ma y double in an effort to maximize converter efficiency. 3. At 230 Vac.
