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

EMC RECOMMENDATIONS
When used in a Class I system implementation (utilizing an Earth Ground connection as depicted in the schematic below),
the PSK-S25B series requires additional inductance and Y-Caps to meet EN55032 Class B. These additional components
are not required in a Class II implementation where no Earth Ground is present.

POWER BOOST
The PSK-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 PSK-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.
