At full load, nominal input, 20 MHz bandwidth oscilloscope, with 1 F ceramic and 10 F electrolytic capacitors on the output. 2. At 230 Vac, full load, 25C. 3. All specifications are measured at Ta=25C, nominal input voltage, and 75% rated output load unless otherwise specified. 4. Parts with the -PB suffix can sustain 2 times the rated output load for 10 seconds (MAX) and 10% duty cycle (MAX). This functionality requires a 33 F / 400 V capacitor connected between pins BC+ and BC-. See Power Boost Section below for more details.
