On the job

The switch-selectable AC input range means one unit covers different mains conditions without swapping hardware. The 200% peak power headroom is worth checking against inrush-heavy loads such as motorised lenses or multi-camera setups drawing on start-up. Free-air convection cooling keeps installs quiet and removes fan maintenance from the service list, and the power-on LED gives a quick visual check of status without opening the case.

The 70°C rated operating temperature and 5000m altitude tolerance give this unit headroom over standard indoor-rated supplies, which is worth factoring in when ambient conditions on a given install run harder than a typical office environment.
