The PS-PRO II Power Conditioner/Sequencers is capable of powering up a rack full of equipment in a 3- step delayed sequence. The sequence is reversed for power-down. The sequence can be initiated with either momentary or maintained switches, locally or remotely. A duplex outlet is provided for each delay step. A front panel screwdriver adjustment sets the delay time for the PS-PRO II. The PS-PRO II also features a locking switch with a removable key for maximum security. One or more Furman PS-PRO II’s may be installed in remote locations and operated via low-voltage wiring. The PS-PRO II includes a rear mounted BNC jack which accepts any standard (12VAC, 0.5A) gooseneck lamp for rear rack illumination, as well as a front panel switch which controls the gooseneck’s operation.

PS-REL Relay Accessory:

Allows a PS-PRO II to be turned on by sensing AC at a preamp’s switched outlet; also allows daisy-chaining for 6 or more delayed outlet groups.
