Crestron ZUMLINK-JBOX-PSU Zūm Link J-Box Power Supply, 4 Ports

It is the Zūm Wired J-Box Power Supply, a junction box mounted unit that delivers additional Zūm Link power to a Zūm wired commercial room. It has four Zūm Link connections that provide communication and power distribution for Zūm Link devices such as keypads, presence detectors and daylight sensors.

Zūm Link output is 250mA per segment and 500mA in total across both segments. Ports 1 and 2 make up segment 1, and ports 3 and 4 make up segment 2. Up to 250mA can pass through, and the cumulative maximum including the internal power supply is 750mA.

Crestron lists Zūm keypads, presence detectors and daylight sensors, all sold separately. These connect to the supply's four RJ-45 Zūm Link ports, which carry both power and Zūm Link communication, so the supply becomes part of the room's Zūm Link wiring along with the load controllers and other devices.

It takes a 100-277VAC, 50/60 Hz input. Line and neutral connect through 14 AWG Class 1 flying leads, black for line and white for neutral. A green PWR LED indicates that power is present. The unit is IP20 rated and designed to operate from 0° to 40°C.

A 1/2 in. conduit knockout secures it to the side of a standard 4 in. square junction box. The housing is white plastic, UL 94 5VA flame rated, and meets UL 2043 requirements. The supply measures 125 mm high, 108 mm wide and 52 mm deep and weighs 199 g (7 oz).
