At full load, nominal input, 20 MHz bandwidth oscilloscope, with 1 µF ceramic and 10 µF electrolytic capacitors on the output. At 230 Vac, full load, 25°C. All specifications are measured at Ta=25°C, nominal input voltage, and 75% rated output load unless otherwise specified. 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 µF / 400 V capacitor connected between pins BC+ and BC-. See Power Boost Section below for more details.

TDK cui.com Additional Resources: Product Page | CUI Inc │ SERIES: VOF-S25B │ DESCRIPTION: AC-DC POWER SUPPLY 3D Model | PCB Footprint date 04/28/2021 │ page 6 of 7 POWER BOOST The VOF-S25B Series has an ordering option called Power Boost (“-PB” suffix), which can double the rated output power provided to the load for a maximum of 10 seconds and repeated duty cycle of 10%. This functionality requires a 33 uF / 400 V capacitor to be connected between the BC+ and BC- pins as depicted in the schematic below. This external capacitor is not required if the VOF-S25B is operating from 220 Vac mains. When utilizing the Power Boost Feature, care must be taken not to thermally overstress the unit. The combined load (nominal plus peak) should not exceed 65% of the full load rating when averaged out over time. INSTALLATION INSTRUCTIONS The mounting holes should all be 1.5 mm in diameter. A minimum of 4 mm clearance is required for all four sides of the unit and a minimum of 5 mm clearance is required above the top surface of the unit. cui.com Additional Resources: Product Page | 3D Model | PCB Footprint CUI Inc │ SERIES: VOF-S25B │ DESCRIPTION: AC-DC POWER SUPPLY date 04/28/2021 │ page 7 of 7 REVISION HISTORY rev. description date 1.0 initial release 02/13/2020 1.01 updates to mechanical & power boost sections 04/08/2020 1.02 circuit figures and derating curves updated 04/28/2021 The revision history provided is for informational purposes only and is believed to be accurate.
