Compliance C-4
AC30V series Variable Speed Drive
EMC Standards Comparison
The standards are concerned with two types of emission
Radiated Those in the band 30MHZ – 1000MHz which radiate into the environment
Conducted Those in the band 150kHz – 30MHz which are injected into the supply.
RADIATED
The standards have common roots (CISPR 11 & CISPR14) so there is some commonality in the test levels applied in different environments.
