The ADM2795E performs robustly in several system-level EMC tests,
which are certified by an EMC compliance test house (certification is
available on request):
IEC 61000-4-5 surge
IEC 61000-4-4 EFT
IEC 61000-4-2 ESD
IEC 61000-4-6 conducted RF immunity
IEC 61000-4-3 radiated RF immunity
IEC 61000-4-8 magnetic immunity
Conclusion
Analog Devices offers a complete signal chain solution for solar
PV and energy storage applications. iCoupler isolated gate driver
solutions include the ADuM4135 and the ADuM4223/ADuM3223,
while iCoupler isolated communication port solutions include the
ADM2795E and ADM2587E, with the ADSP-CM419 mixed-signal
control processor offering a power communication and control
interface. iCoupler isolation provides a safe, reliable, and EMC robust
solution for solar PV network communication interfaces.
Analog Devices' interface and isolation portfolio has several options
for isolating your RS-485 interface. The ADM2795E provides a
complete, system-level EMC solution with compliance to IEC 61000
surge, EFT, and ESD standards, as well as immunity to conducted,
radiated, and magnetic disturbances, which are common in harsh
solar PV environments. The ADM2795E reduces time to market for
designs that need to meet strict regulatory targets.
Signal and power isolated RS-485 transceivers, such as the
ADM2587E, provide the most integrated signal and power isolated
solution available on the market today. The ADM2587E can be used
in a RS-485 repeater design to provide a path to adding iCoupler
isolation robustness in designs that are already completed.
