We are making an offline 240VAC SMPS which after being installed, will firstly charge up a 24V battery at 5A for 3 hours. Then it will simply sit there for the next 10 years drawing about 2W of standby power, as the equipment continuously monitors some safety valves which should be actuated in case of emergency. The 24V battery also needs to be kept topped up with a “float” charge, but this is only part of the 2W standby power.
As such, is there some clause in the EN61000-3-2 standard which we can invoke in order for us to avoid using a PFC stage?
I mean, our average power draw is so low that surely a PFC stage would not be mandated for this?
I found the below, which is relevant , but not conclusive on this subject….
