When the output voltage is increased, the total output power cannot exceed the nominal output power. 2. If the total output power exceeds the nominal output power, it can be maintained for a maximum of 10 seconds, but not repeated for at least 30 minutes. The power supply cannot exceed the transient power. 3. At full load, nominal input, 20 MHz bandwidth oscilloscope, tip & barrel method, output terminated with 47 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. 4. At 230 Vac.
