The equipment typically includes an embedded AC-DC converter, or power supply, which might also be chassis-mount or sometimes rack- or PCB-mounted. In each case, the power supply will invariably meet the statutory requirements for emissions as a stand-alone part, typically EN55011/EN55032 for conducted and radiated interference. But additional filtering may still be necessary.
