CISPR 11: Group 1, Class A
Group 1: Equipment has intentionally generated and/or uses
conductively-coupled radio frequency energy that is necessary for
the internal function of the equipment itself.
Class A: Equipment is suitable for use in all establishments other
than domestic and those directly connected to a low-voltage
power supply network that supplies buildings used for domestic
purposes. There may be potential difficulties in ensuring
electromagnetic compatibility in other environments due to
conducted and radiated disturbances.
Emissions that exceed the levels required by CISPR 11 can occur
when the equipment is connected to a test object.
Equipment)
Class A: Equipment meets requirements for industrial
electromagnetic wave equipment and the seller or user should
take notice of it. This equipment is intended for use in business
environments and not to be used in homes.
