The Sony UNI-PBU1 Power Block Unit Case is an outdoor power supply that is enclosed in a rugged, IP66-rated, vandal-resistant aluminium enclosure. It is designed for use with the UNI-WMB1 Wall Mount and the UNI-MDB1, UNI-MDB2, and UNI-MDB3 Pendant Adapter Kits, which can be directly mounted to the Power Block's hinged door.

The IP66 and NEMA 4X rated unit is protected against the ingress of dust, wind, rain, high pressure water jets from any direction, hose-directed water, and damage from external ice formation. This unit comes standard with an 84 VA power supply, designed for either 220 or 120 VAC input with 24 VAC output. In addition, it provides 52 W power to the heater/blower and 32 W power to the camera.
