– PSU for USA
To comply with US regulations that apply to outdoor deployments of mains power supplies, a special
US version of the AirSynergy power supply has been produced with the PSU module and the mains
connecting blocks enclosed in a small NEMA approved enclosure. The mains cable and 48V power
cables are brought through the weatherproof glands provided. This type of power supply (SYN-PSU-
ODUL-AC-1) must be used for all deployments in the USA.
