Description：gnetic

The F48/F481 series model is a Desk-Top power adapter with a plastic shell design, which can eﬀectively prevent users fromcompatible
Electromagnetic

electrical hazards. Its working eﬃciency meets the latest energy eﬃciency requirements. It can work safely and eﬀectively in ancompatibility immunity

ambient temperature of 0℃ to 40℃. It has complete protection function and is also in line with the relevant certiﬁcation of electronic
information & audio and video(IEC60950、IEC60065、IEC62368). It uses 48W shell, and 18# wire to be compatible with level 5 or 6
energy eﬃciency. The lightning strike meets 6KV. EMC is designed with Y-cap.

1. All speciﬁcations and parameters shall be measured at the input of 230VAC, rated load and ambient temperature of 25℃ unless otherwise speciﬁed.
2. Ripple and noise measurement method: capacitance of 0.1uF and 47uF in parallel at the terminal and the measurement is performed under the 20MHZ bandwidth.
3. Accuracy: includes setting error, linear adjustment rate and load adjustment rate.
4. The power supply adapter is an independent component, but the ﬁnal adapter still needs to be conﬁrmed in co nnection with the electromagnetic compatibility ofthe terminal equipment.
