Notes: 1. At full load, nominal input, 20 MHz bandwidth oscilloscope, with 0.1 µF ceramic and 10 µF electrolytic capacitors on the output. For model VOF-S60B-5, add a 0.1 µF ceramic and 47 µF electrolytic capacitors on the output. 

2. At 230 Vac, full load, 25°C. 

3. 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 100 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 VOF-S60B 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 VOF-S60B 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 100 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-S60B is operating from 230 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.
