## **PEAK LOAD FUNCTION** 

The series includes a peak load function capable of delivering twice its rated power. If Vin < 200 Vac then a 68 µF, 400 Vdc capacitor needs to be placed on the BC+ and BC- pins to support peak load. If Vin > 200 Vac then the supply supports peak load without the additional capacitor. 

The peak load current must be less than 10 seconds and less than 10% duty cycle. 

When operating with peak load, the non-peak load level must be less than 80% of the rated output power.

## **CLASS I EMI RECOMMENDED CIRCUIT** 

The series requires additional inductance and YCap to comply with EN 55032 Class B standards under Class I test conditions. If customers are using Class II systems, this section can be disregarded.
